I Am Starving Hungry Hungry Hippos T-ShirtThis Hungry Hungry Hippos shows one of the mechanical hippos from the classic board game. The shirt reads I Am Starving! When players sit down to play Hungry Hungry Hippos, the board is surrounded by four mechanical, colorful, plastic hippopotamuses operated by levers on their back. When the lever is pressed, the hippo opens its mouth and extends its head forwards on a telescopic neck. When the lever is released, the head comes down and retracts.
