Tadpoles start out in little eggs.
Tadpoles grow and grow in the eggs.
Tadpoles move in the egg.
Tadpoles swim, eat, and sleep.
Then, tadpoles' legs begin to grow.
The back legs are bigger than the front legs.
Soon, tadpoles have four legs and a tail.
Next, tadpoles have four legs and no tail.
A frog!
