The game was ported to arcade by Universal in 1984. The ZX Spectrum 16K version features a daring explorer named Jack who jumps up through the holes, avoiding large monsters. Each monster kicks him and he can fall down through the holes, eventually losing a life. He runs making a funny noise, and after each level song lyrics are revealed, rhyme by rhyme.
