metamorphosis: The process of big changes in an animal's body as it grows up
tadpole: A young frog that lives in water, has a tail, and breathes through gills
adult: A fully grown animal that can reproduce and have young of its own
reproduce: To make babies or offspring of the same kind
hatch: To break out of an egg
grow: To get bigger and develop over time
offspring: The babies or young of an animal
