Hungry Hippos

Which animal's name would best follow hungry?You can imagine the advertising execs musing whilst hinking outside the box- Hyenas? No. Hares? No. Er,  Hammerhead Sharks? No!!. and thus one of the noisiest and frantic of kids games was born involving you pounding the retractable mouths of one of four Hippos attempting to swallow as many small white marbles as possible. Was it fun? Briefly. Were you allowed to play it whilst your dad was watching Grandstand? Certainly not!
