What happens in the animal kingdom?! Do all animals live in peace? Not at all: some animals are afraid of each other, and others eat each other. An elephant is afraid of a mouse, the mouse is eaten by a fox, the fox loses to a lion, and finally, the lion is defeated by... two lions! Frank's Zoo uses this order of animals in a fun way. Eat or be eaten! An animal can also be defeated by a larger number of the same animal! The sixty colorful animal cards are shuffled and dealt among the players. Each card depicts an animal. Above this animal is a cloud depicting the animals that can defeat it. Some animals can be defeated by many animals, and others by fewer.
