He is a yellow rabbit animatronic being slightly shorter than Fredbear and wears a single black button on his chest. It is possible that Spring Bonnie wears a bowtie (as shown from his poster hallucination at CAM 02 and CAM 10 in the third game). His body structure is nearly identical to that of a human. He sports a pair of three-jointed ears and a round, fluffy tail which is seen while he's on the left side of the stage from the Night 5 minigame. Unlike his newer counterpart, Bonnie, he doesn't seem to carry a guitar, which could mean he is a back-up singer, rather than a guitarist.
