You know how people have coffins when they die and they go in the ground? Well, sometimes people find little coffins for frogs too! It's not that frogs are dying and need the coffins, it's more like a way to keep them safe and make sure they don't get hurt. The frog coffin is usually a little box or container that has a lid on it. People might put a frog in there if they're studying it or if they want to keep it safe from other animals. It's like a home for the frog that it can go in and out of whenever it wants. It's important to take care of frogs because they are living creatures just like us, and we should always try to treat them with kindness and respect.
