Roommate

Brainy's new roommate is peeking through the bars at the top of the cage. He does look a little bit like this guy, don't you think?

The Little Prince named him Climby, because he does a lot more of this than Brainy ever did.

They both become the most brilliant green when they are not hiding under rocks.

And if you are wondering where they live, here is home sweet home, complete with rainbows.
