Roller Coaster Hippo is a party game where players have to answer questions, mime, or model objects in clay. The hippopotamus who reaches the finishing line first, wins. Along the way, players are given funny tasks and participate in crazy events. Play typically lasts approximately one hour, although a 30-minute game is also described in the rules. This game has also been released in an advanced version as Ein Nilpferd kommt selten allein (Hippofolies Master)
