Toy Bonnie sports a red bow tie, black button nose, whisker spots, and buck teeth, unlike his original counterpart, similar to that of a stereotypical rabbit. His eyes appear articulated, as if he can move them freely. In a paranormal manner, his pupils grow smaller the closer he gets to the player.

Toy Bonnie has a high-pitched, robotic voice that some find annoying, even comparing it to a chipmunk's. The voice is delivered with a confident, even arrogant, tone, which some players appreciate as fitting the character.
