This childrens game features a plastic toy carnivorous plant whose mouth is hinged so that it slams shut. To play, players take turns placing marbles into the mouth. If the mouth remains open, your turn is over. If the mouth snaps shut, you're out of the game. The last player remaining wins.For an advanced game players are given an equal number of red and black marbles. On a turn you roll a die and place the colored marble indicated into the mouth. If it stays open, your turn is over. If it snaps shut, you must take all the marbles in the mouth and add them to your other marbles. The winner is the first player to get rid of all their marbles. - BoardGameGeek
