Pipi & Bibis / Whoopee!! (Z80 sound cpu, set 1)

Pipi & Bibis is a platform game for one or two players, in which the aim is to infiltrate buildings and plant time bombs at the computer terminals that litter the levels. The planting of the final bomb starts the detonation sequence, players must then quickly reach the level's exit before the bombs explode.

Each level is populated with enemy scientists and agents, and any contact with these will result in the loss of a life. To help combat this, players are armed with a 'stun gun' which will knock the enemy to the floor, allowing the player to pass. If an enemy is held in the stun gun's beam for several seconds, the enemy will fall to the platform below.

At the completion of each level, part of a cartoon picture of woman in a state of undress is shown. The entire picture is revealed once every four levels.
