There are four hippos in the game: Lizzie (funnily enough) Hippo (purple), Henry Hippo (orange), Homer Hippo (green), and Harry Hippo (yellow). In some versions of Hungry Hungry Hippos, Henry is replaced by a blue hippo of the same name. A later edition of the game replaces the purple hippo, Lizzie, with a pink one named Happy. The most recent edition of the game (in Fall 2009) has a lighter blue base with pastel colored versions of the Hippos: Sweetie Potamus (pink), Bottomless Potamus (yellow), Picky Potamus (orange), and Veggie Potamus (green).
So there you go next time you see Hungry Hungry Hippos you can bore people with some trivia.
