Tree is, well, a tree. It has the stereotypical appearance, brown wood with green leaves. It also has a mouth and a microphone that appears to be floating somehow. In its mad form, its wood turns into a lighter brown and its leaves turn red. it now also has visible red glowing eyes. In its super mad form, its leaves are now fully black. It now has a much more evil appearance, with bigger eyes and a big red mouth. 
The tree is pansexual, and is dating Jared. It also likes being alone.
