Mr. Tree is Stinky's potted tree which is brought in by Stinky in the fifteenth season 1 episode of The Animal Show. In the episode, Stinky believes that Mr. Tree might be eaten by today's guests because they hurt them, but Jake informs him that they don't. When Alexis the Giraffe is introduced, she mistakes Mr. Tree as dinner, while Stinky tries not to have her eat his beloved tree. She promises not to even nibble on the tree as she informs them that giraffes only eat the old growths of the tree for it to grow stronger branches and leaves. After she leaves, Stinky has Mr. Tree introduce Baby Talk. After the footage of a giraffe calf on Baby Talk, Stinky says that it reminds Mr. Tree of how he used to be a little sapling learning how to grow branches. After a song called "The Tree Song," Stinky thinks that Mr. Tree wishes that there should be more trees on the show. Mr. Tree is very good at answering Tizzy's hard questions, especially those which Jake gets wrong. When Lamont the Sloth arrives, Stinky wants him to explain why sloths destroy trees, but Lamont claims that sloths love trees and how they live, eat from, and sleep in them. Stinky believes that Mr. Tree moves faster than Lamont. Stinky claims that Mr. Tree cannot sing, not because trees cannot sing, because he forgot his music. Stinky assures Mr. Tree that Jake always does tell good stories, just like today's story, which just happens to be about trees. Mr. Tree gives the story two limbs up. Mr. Tree is also very good at waving goodbye with a branch as an arm.
