Hungry Hungry Hippos is a tabletop game made for young children, produced by Hasbro, under the brand of its subsidiary, Milton Bradley. The purpose of the game is for each player to collect as many marbles as possible with his or her ‘hippo’ (a toy hippo model). The gameboard is surrounded with mechanical, colorful, plastic hippopotami operated by players through repetitive smacking on the back (of the hippo). White plastic marbles are poured over the board, and the players repeatedly slap down on their controllers, thus lengthening their necks in order to snag more marbles, which roll through the hollow interior of each hippopotamus and into a moat enveloping the gameboard. The game continues until all marbles have been devoured, and it is then that a winner is decided depending on the player with the largest quantity of marbles.
