If you want to observe them closely, make sure that you have a small container of water to keep them in. A metamorph is the in-between stage, when a tadpole is changing into a frog. When all four legs of a tadpole start to show, that's when we first call it a metamorph. Just like tadpoles, metamorphs are squishy, so be extra careful if you handle them. Their bodies need to stay wet or they will dry out, and die very quickly.
Frogs are wiggly and wet and can be hard to hold.
If you handle one, make sure you don't squish it. They also need to stay wet, just like tadpoles and metamorphs. It upsets frogs to be crowded, and that can sometimes make them very sick. So don't put more than 1-2 frogs in one container for more than a few minutes. This is one of those times when it's handy to have an extra person around.
