Preschool game produced by Milton Bradley, now a part of game mega-conglomerate Hasbro, in which the players encourage small, plastic, pastel-colored hippopotamus proxies to devour marbles for the greater honor of player and species. The loud, repetitive noises produced by the plastic hippos as they feed is hated by four out of five parents who hate loud, repetitive noises.

Oddly enough, this game exists in an arcade version, produced by Cromptons Leisure Machines Ltd., with pressurized air serving the marbles for mechanical hippos to devour.

The lyrics to the recent commercial (Goodbye, cruel world):

They're hungry, hungry hippos!
They're hungry, hungry hippos!
They're hungry, hungry hippos!
It's time to feed your face,

They're hungry, hungry hippos!
They're hungry, hungry hippos!
They're hungry, hungry hippos!
They're in an eating race!

Hurrah.
