Gameplay
Since Cosmi is vulnerable in his small alien form, he must first beam up a nearby earthling in order to create a disguise for himself. Once he has beamed a person up, he can change his form by stepping under a UFO. Each earthling has a different ability that can be used for causing mischief, such as boomboxes, vacuum cleaners or bazookas. Successfully knocking over earthlings yields coins that are required to complete the goals set in each level. Once pranked, the earthlings will become hostile towards Cosmi and try to attack him. While disguised, Cosmi can take two hits, the first leaving him in underwear (a possible homage to Ghosts'n Goblins), while the second one reverts him to his vulnerable alien form. Earthlings will continue to chase and attack Cosmi, forcing him to lose coins, until he can find another UFO to change into another disguise. At certain points in the level, a Panic Time will occur where something crazy in the stage happens for a short amount of time.
