Long before he was a megalomaniacal, Elvis-impersonating, psychotic, brain-transferring mad scientist, Dr. Lunatic was a young boy, exploring the kingdom of Loonyland. Follow his first adventure in Halloween Hill, where he takes on the freakish inhabitants with an array of even more freakish weapons like a potted cactus and whoopee cushion. This is an action-adventure game, where you must explore to improve Loony's abilities and gain access to ever more dangerous areas, all in an effort to find out what lies behind the madness going on in Halloween Hill.
