A reaction game for children. The crocodile is hungry and tries to catch the frog; the frogs try to flee when the crocodile gets activated.
One player is the crocodile player and turns over cards with various animals. When an awake and hungry crocodile shows up, the crocodile player hits the button to close the big mouth, and the other players hit their buttons to make their frogs jump away. If your frog gets catched, you get a bite marker; there are also penalties for trying to flee at the wrong moment (for example at the sleeping crocodile card).
A player with 5 bite markers is out of the game. Last frog player wins; the crocodile player can't win.
According to the box cover, the game needs 2 batteries. They are only necessary for the voice output, not for the mechanic.
