Doodle is a fictional character from an unknown species who's physical appearance has recently been determined.
(S)he is a bubbly, warm, kind hearted, and very silly being.
Doodle is said to have different phases of appearances, but only one has been shown, presumably in it's first phase. In this form, it looks like a square shaped marshmellow with no legs, but two arms sticking out on one side each. On its head is what appears to be chocalate fudge, or perhaps a ice cream cone.
