Day of the Tentacle, also known as Maniac Mansion II: Day of the Tentacle,[1][2] is a 1993 graphic adventure game developed and published by LucasArts. It is the sequel to the 1987 game Maniac Mansion. The game's plot follows Bernard Bernoulli and his friends Hoagie and Laverne as they attempt to stop the evil Purple Tentacle—a sentient, disembodied tentacle—from taking over the world. The player takes control of the three and solves puzzles while using time travel to explore different periods of history.

Dave Grossman and Tim Schafer co-led the game's development, their first time in such a role. The pair carried over a limited amount of elements from Maniac Mansion and forwent the character selection aspect to simplify development. Inspirations included Chuck Jones cartoons and the history of the United States. Day of the Tentacle is the eighth LucasArts title to use the SCUMM engine, and the company's first title to feature voice acting.

The game was released simultaneously on floppy disk and CD-ROM to critical acclaim. Critics focused on its cartoon-style visuals and comedic elements. Day of the Tentacle has featured regularly in lists of "top" games published more than a decade after its release, and aspects have been referenced in popular culture.



Day of the Tentacle follows the point-and-click two-dimensional adventure game formula, first established by the original Maniac Mansion. Players direct the controllable characters around the game world by clicking with the computer mouse. To interact with the game world, players choose from a set of commands arrayed on the screen (such as "pick up", "use", or "talk") and then on an object in the world. This was the last SCUMM game to use the original interface of having the bottom of the screen being taken up by a verb selection and inventory; starting with the next game to use the SCUMM engine, Sam & Max Hit the Road, the engine was modified to scroll through a more concise list of verbs with the right mouse button and having the inventory on a separate screen.[3][4]

Day of the Tentacle uses time travel extensively; early in the game, the three main protagonists are separated across time by the effects of a faulty time machine. The player, after completing certain puzzles, can then freely switch between these characters, interacting with the game's world in the separate time periods. Certain small inventory items can be shared by placing the item into the "Chron-o-Johns", modified portable toilets that instantly transport objects to the other time period, while other items are shared by simply leaving the item in a past time period to be picked up by a character in a future period. Changes made to a past time period will affect a future one, and many of the game's puzzles are based on the effect of time travel, aging of certain items, and alterations of the time stream. For example, one puzzle requires the player, while in the future era where Purple Tentacle has succeeded, to send a medical chart of a Tentacle back to the past, having it used as the design of the American flag, then collecting one such flag in the future to be used as a Tentacle disguise to allow that character to roam freely.[5]

In Maniac Mansion, the playable characters can be killed by various sequences of events. LucasArts adopted a different philosophy towards its adventure games in 1990, beginning with Loom. Their philosophy was that the game should not punish the player for exploring the game world. Accordingly, in most LucasArts adventure games released after Loom, including Day of the Tentacle, the player character cannot die.

The whole original Maniac Mansion game can be played on a computer inside the Day of the Tentacle game; this practice has since been repeated by other game developers, but at the time of Day of the Tentacle's release, it was unprecedented.[6]


Five years after the events of Maniac Mansion, Purple Tentacle—a mutant monster and lab assistant created by mad scientist Dr. Fred Edison—drinks toxic sludge from Dr. Fred's laboratory. The sludge causes him to grow a pair of flipper-like arms and develop a vastly increased intelligence and a thirst for global domination.[7] Dr. Fred plans to resolve the issue by killing Purple Tentacle and his harmless, friendly brother Green Tentacle, but before he can Green Tentacle sends a plea of help to his old friend, the nerd Bernard Bernoulli. Bernard travels to the Edison family motel with his two housemates, deranged medical student Laverne and roadie Hoagie, and frees the tentacles. Purple Tentacle escapes to resume his quest to take over the world.[8]

Since Purple Tentacle's plans are flawless and unstoppable, Dr. Fred tries to use his Chron-o-John time machines to send Bernard, Laverne and Hoagie to "yesterday" to turn off the sludge-producing machine, thereby preventing Purple Tentacle's exposure to the sludge.[9] However, since Dr. Fred only used an imitation diamond as a power source, the Chron-o-Johns break down in operation. Laverne is deposited 200 years in the future, where humanity has been enslaved and Purple Tentacle rules the world from the Edison mansion, while Hoagie is dropped 200 years in the past, where the motel is being used by the Founding Fathers to write the United States Constitution. Bernard is returned to the present, where he must acquire a real diamond for Dr. Fred to repair the time machine.[10] Meanwhile, the others must restore power to their own Chron-o-Johns; Hoagie recruits the help of Benjamin Franklin and Dr. Fred's own ancestor to create a superbattery, while Laverne evades capture by the tentacles long enough to run an extension cord to her unit. The three send small objects back and forth in time through the Chron-o-Johns and make changes to history to help the others complete their tasks.

Eventually, Bernard uses Dr. Fred's family fortune of royalties from Maniac Mansion to purchase a real diamond, both Laverne and Hoagie manage to power their Chron-o-Johns, and the three are reunited in the present. Purple Tentacle arrives, hijacks a Chron-o-John and takes it to the previous day to prevent them from turning off the sludge machine; he is pursued by Green Tentacle.[11] Dr. Fred attempts to send Bernard, Hoagie and Laverne to the previous day again, this time successfully. Upon arriving, the three discover Green Tentacle has been incapacitated, while Purple Tentacle has used the time machine to bring several versions of himself to the same day to stop them from turning off the sludge machine.[12] Bernard and his friends successfully defeat all the Purple Tentacles, turn off the machine and prevent the whole series of events from ever happening. The game ends with the credits rolling over a tentacle-shaped American flag, one of the more significant results of their tampering in history.


Tim Schafer and Dave Grossman co-led development of the sequel to Maniac Mansion, their first time directing a game.

Following a string of successful adventure games, LucasArts assigned Dave Grossman and Tim Schafer to lead development of a new game. The two had previously assisted Ron Gilbert with the creation of The Secret of Monkey Island and Monkey Island 2: LeChuck's Revenge, and the studio felt that Grossman and Schafer were ready to manage a project. The company believed that the pair's humor matched well with that of Maniac Mansion and suggested working on a sequel. The two developers agreed and commenced production.[13] Gilbert and Gary Winnick, the creators of Maniac Mansion, collaborated with Grossman and Schafer on the initial planning and writing.[13][14]

Creative design

In planning the plot, the four designers considered a number of concepts, eventually choosing an idea of Gilbert's about time travel that they believed was the most interesting. Grossman and Schafer decided to carry over previous characters that they felt were the most entertaining. The two considered the Edison family "essential" and chose Bernard because of his "unqualified nerdiness". Schafer and Grossman planned to use a character selection system similar to the first game, but felt that it would have complicated the design process and increased production costs. Believing that it added little to the gameplay, they removed it early in the process and reduced the number of player characters from six to three.[13] The dropped characters included Razor, a female musician from the previous game; Moonglow, a short character in baggy clothes; and Chester, a black beat poet. Ideas for Chester, however, morphed into new twin characters in the Edison family.[14] The smaller number of characters reduced the strain on the game's engine in terms of scripting and animation.[3]

The staff collaboratively designed the characters. They first discussed the character personalities, which Larry Ahern used to create concept art. The drawings inspired further ideas from the designers. Chuck Jones cartoons like Rabbit of Seville, What's Opera, Doc? and Duck Dodgers in the 24½th Century inspired the artistic design. Grossman also cited cartoons featuring Pepé Le Pew, and commented that the gag involving a painted white stripe on Penelope Pussycat inspired a puzzle in the game. The artists spent a year creating the in-game animations. Peter Chan designed backgrounds, spending around two days to progress from concept sketch to final art for each background.[14] The script was written in the evening, when fewer people were in the office.[13][14] Grossman considered it the easiest aspect of production, but encountered difficulties when writing with others around.[13]

With a time travel story, I leave a bottle of wine somewhere, and it causes a bottle of vinegar to appear in the same place four hundred years later. Same basic idea: I do X over here, and it causes Y over there. Whether ‘over there’ means in the next room or 400 years in the future is irrelevant. I will say that it was really fun to think about the effects of large amounts of time on things like wine bottles and sweaters in dryers, and to imagine how altering fundamentals of history like the Constitution and the flag could be used to accomplish petty, selfish goals like the acquisition of a vacuum and a tentacle costume. We definitely enjoyed ourselves designing that game.

Dave Grossman on designing the game's puzzles[14]

Grossman and Schafer brainstormed regularly to devise the time travel puzzles, and collaborated with members of the development team as well as other LucasArts employees. They would identify puzzle problems and work towards a solution similar to how the game plays. Most issues were addressed prior to programming, but some details were left unfinished to work on later.[13] The staff conceived puzzles involving the U.S.'s early history based on their memory of their compulsory education.[14] To complete the elements, Grossman researched the period to maintain historical accuracy, visiting libraries and contacting reference librarians. The studio, however, took creative license towards facts to fit them into the game's design.[13][14]

Technology and audio

Day of the Tentacle uses the SCUMM engine developed for Maniac Mansion.[13] LucasArts had gradually modified the engine since its creation. For example, the number of input verbs was reduced and items in the character's inventory are represented by icons rather than text.[3] While implementing an animation, the designers encountered a problem later discovered to be limitation of the engine. Upon learning of the limitation, Gilbert reminisced about the file size of the first game. The staff then resolved to include it in the sequel.[13]

The title was the first LucasArts adventure game to incorporate voice work.[Note 1] Voice director Tamlynn Barra managed that aspect of the game. Schafer and Grossman described how they imagined the characters' voices and Barra sought audition tapes of voice actors to meet the criteria. She presented the best auditions to the pair. Schafer's sister Ginny was among the auditions, and she was chosen for Nurse Edna. Schafer opted out of the decision for her selection to avoid nepotism.[13] Grossman and Schafer encountered difficulty selecting a voice for Bernard.[13][14] To aid the process, Grossman commented that the character should sound like Les Nessman from the television show WKRP in Cincinnati. Barra responded that she knew the agent of the character's actor, Richard Sanders, and brought Sanders on the project.[13][15] Denny Delk and Nick Jameson were among those hired, and provided voice work for around five characters each.[13] Recording for the 4,500 lines of dialog occurred at Studio 222 in Hollywood. Barra directed the voice actors separately from a sound production booth. She provided context for each line and described aspects of the game to aid the actors.[16]

Day of the Tentacle was one of the first games concurrently released on CD-ROM and floppy disk.[16] A floppy disk version was created to accommodate consumers that had yet to purchase CD-ROM drives. The CD-ROM format afford the addition of audible dialog. The capacity difference between the two formats necessitated alterations to the floppy disk version. Grossman spent several weeks reducing files sizes and removing files such as the audio dialog to fit the game onto six diskettes.[14]


Day of the Tentacle was critically acclaimed. Charles Ardai of Computer Gaming World wrote, "Calling Day of the Tentacle a sequel to Maniac Mansion [...] is a little like calling the space shuttle a sequel to the slingshot".[17] The reviewer enjoyed the game's humor and interface, and praised the designers for removing "dead end" scenarios and player character death. He lauded its voice acting with the statement that it "would have done the late Mel Blanc proud", and compared the game extensively to "Looney Toons gems from the 40's and 50's"—particularly with regard to its humor, animation and camera angles. The review ended with the statement that "I expect that this game will keep entertaining people for quite some time to come".[17] Sandy Petersen of Dragon stated that its graphics "are in a stupendous cartoony style", while praising its humor and describing its sound and music as "excellent". Although the reviewer considered it "one of the best" graphic adventure games, he noted that, like LucasArts' earlier Loom, it was extremely short; he wrote that he "felt cheated somehow when I finished the game". He ended the review, "Go, Lucasfilm! Do this again, but do make the next game longer!".[18]

Phil LaRose of The Advocate called it "light-years ahead of the original", and believed that its "improved controls, sound and graphics are an evolutionary leap to a more enjoyable gaming experience". He praised the interface, and summarized the game as "another of the excellent LucasArts programs that place a higher premium on the quality of entertainment and less on the technical knowledge needed to make it run".[19] The Boston Herald's Geoff Smith noted that "the animation of the cartoonlike characters is of TV quality", and praised the removal of dead ends and character death. He ended, "It's full of lunacy, but for anyone who likes light-hearted adventure games, it's well worth trying".[20] Vox Day of The Blade called its visuals "well done" and compared them to those of The Ren & Stimpy Show. The writer praised the game's humor, and stated that "both the music and sound effects are hilarious"; he cited the voice performance of Richard Sanders as a high point. He summarized the game as "both a good adventure and a funny cartoon".[21]

Lim Choon Wee of the New Straits Times highly praised the game's humor, which he called "brilliantly funny". However, the writer commented that the game's puzzles relied on "trial and error" with "no underlying logic". He stated that the game "remains fun" despite this issue, and finished by describing Day of the Tentacle as "definitely the comedy game of the year".[22] Daniel Baum of The Jerusalem Post called it "one of the funniest, most entertaining and best-programmed computer games I have ever seen", and lauded its animation. He wrote that the game provided "a more polished impression" than either The Secret of Monkey Island or Monkey Island 2: LeChuck's Revenge. The writer stated that its high system requirements were its only drawback, and believed that a Sound Blaster card was required to fully appreciate the game.[23] In a retrospective review, Adventure Gamers' Chris Remo wrote, "If someone were to ask for a few examples of games that exemplify the best of the graphic adventure genre, Day of the Tentacle would certainly be near the top".[24]


Day of the Tentacle has featured regularly in lists of "top" games. Adventure Gamers included the game as the top entry on its 20 Greatest Adventure Games of All Time List in 2004.[25] The game has appeared on several IGN lists. The website rated it number 60 and 84 on its top 100 games list in 2005 and 2007, respectively.[26][27] IGN named Day of the Tentacle as part of their top 10 LucasArts adventure games in 2009,[28] and ranked the Purple Tentacle 82nd in a list of top 100 videogame villans in 2010.[29] ranked it at number 30,[30] and GameSpot listed Day of the Tentacle as one of the greatest games of all time.[6]

Elements of Day of the Tentacle have appeared in facets of popular culture. Enthusiasts have created fan art depicting the tentacle characters, as well as participated in cosplay based on them.[31] Fans also created a webcomic, The Day After the Day of the Tentacle, using the game's graphics.[27] The 1993 LucasArts title Zombies Ate My Neighbors features a stage dedicated to Day of the Tentacle. The artists for Day of the Tentacle shared office space with the Zombies Ate My Neighbors development team. The team included the homage after frequently seeing artwork for Day of the Tentacle during the two games' productions.[32] In describing what he considered "the most rewarding moment" of his career, Grossman stated that the game's writing and use of spoken and subtitled dialog assisted a learning-disabled child in learning how to read.[13] Telltale Games CEO Dan Connors commented in 2009 that an episodic game based on Day of the Tentacle would be "feasible". However, he cautioned that such an endeavor would hinge on the sales of the Monkey Island titles released that year.[Note 2][33]
