This children's game is as much of a toy as it is a game. Each player has a plastic hippo that is arranged around a plastic arena. When you push the tail it will reach its head onto the playing field - perhaps trapping one or more marbles to be pulled back to a private player marble gutter, perhaps just sending marbles bouncing around the playing field.Some marbles are released onto the playing area players attempt to get their hippos to eat as many marbles as possible. - BoardGameGeek
