Mr. Turtle

Mr. Turtle makes his first, and only appearance in "City of Thieves". He is shown stealing a ruby and inserting it into the larger ruby on top of his head. Not much is known about him, but it is possible that he may be royalty due to the ruby crown he wears. He also has a jetpack within his shell, which he used to escape from Finn and Jake before they could "purify" him.
