Oh lawdy, lawdy! The evil and villainous Krudd, a malignant and nasty race of an evil sort, have decided that the latest thing in badness is to swipe away large amounts of the Earth's baby population! Once the infants are swiped, the naughty aliens transport them back to the planet Krudd where the unsuspecting cherubs are quick frozen into suspended animation. The Krudds plan to sell off the babes as popsicles to the baby-eating Vlurgs From Behind The Moon. Well, a hero is needed and you are that very hero, a wobbling fat blob with a predilection to walking sideways.
Transported into the alien's baby holding warehouse, you must waddle round, collecting babies and saving them from the gory fate lurking just around the corner. Babies are returned home by placing them into the Magic Pram, a mystical object from the planet Muvirkare that teleports any children placed within it back home. For every four babies collected and teleported, a burst of pleasure surges through you, resulting in an extra life quite handy, considering the amount of lives that you'll lose facing the Krudd babyguards.
The format of Kidnap is extremely similar to a lot of other games in short it's an arcade adventure in classic Jet Set Willy style. You can go left, right and jump and babies are collected by travelling over them. Around the gaff are a number of deadly nastier all of which must be avoided: their touch is deadly. As with most games of this type, guiding the fatty under your hypnotic control off the screen causes another screen to splash into view. To complete the game, all of earth's thirty two frozen babies have to be magic prammed back to their snug little cots back home.
