Frogs are a gardener’s friend. They act like natural pest control eating slugs, snails and other pests. If you have a pond already, you might soon see frog spawn, as this is the time of year ...

They soon drop off. Now tiny frogs hop away from the pond. As they grow, they'll discover new things to eat, like slugs and insects. There's a special word for this amazing change. Metamorphosis.
