Pipi & Bibi's

Pipi & Bibi's was a game produced by Toaplan, the makers of Hellfire and Zero Wing. The main objective was to control your character around a room while avoiding enemies, plant bombs in certain locations, and get back to the exit before the bombs exploded. You could play as one or two characters.

For each stage completed, 1/4 of a shadow of a woman would be unlocked. After beating four stages in a row, you would get to view a cartoon picture of a woman in lingerie.
