So here's how the animal game works:
Someone picks an animal, and then someone else picks an animal that can eat it, and so on and so on...
(See how long it can keep going while making sense... eg.. the cat can't eat the lion.)
Example:
1. Worm
2. My bird eats your worm.
3. My dog eats your bird.
3. My bear eats your dog.
I'll start.
My ant eats your aphid.
