Is a baby koala as big mouse?

That's a funny thought! A baby koala is definitely much bigger than a mouse.

Here's why:

* Koala babies are called joeys. They are born very small, about the size of a jellybean!

* Joeys stay in their mother's pouch for about 6 months. During this time, they grow a lot and start to resemble miniature koalas.

* Even at 6 months, a joey is still quite small but much larger than a mouse. They are about the size of a kitten.

So, while baby koalas are tiny, they are definitely bigger than a mouse.
