Some space pore is unintentionally brought back to Earth by a space exploration team and it soon grows into a gigantic chicken-lizard monster who also looks a bit like a doped-out great grandpa of a Teletubby with a pair of cool Martian antenas. No man-made weapon can harm it while he follows in Godzilla's footsteps (quite literally) by stomping around the city of Tokyo and the entire Kanto area.
