Compared to the other redesigns, Toy Bonnie seems to have undergone the most drastic changes.
He is colored a bright shiny blue, with his belly and the insides of his ears colored a pale, powder blue. He has green eyes, purple eyelids, long eyelashes, and rosy red, blushed cheeks.
He also has a white circular tail which is best seen when he is crawling through the Right Air Vent.
Like the other "Toy" redesigns, he is much smoother in texture compared to the original animatronics. He also has a more modernized appearance, bearing multi-joint fingers and a hard casing, as opposed to the fabric covers of the originals.
Toy Bonnie also sports a red bow tie, whisker spots, and buck teeth. His eyes also appear articulated, as if he can move them freely. His pupils grow smaller the closer he gets to the player.
Like the original Bonnie, when on stage, Toy Bonnie holds a guitar, which is red and white with a black neck. However, unlike his counterpart, Toy Bonnie can be seen with his guitar while absent from the Show Stage.
An intriguing, yet disturbing detail is that Toy Bonnie's pupils become smaller when entering the player's office and attacking, as if the pupils contracted like organic eyes. This, however, is unlikely, as when the player shines the Flashlight directly on Toy Bonnie's face his pupils do 'not' contract despite the amount of light being absorbed - his close-up on the Party Room 4 monitor is a good example of this. Why and how this occurs is unknown, and is likely aesthetic.
He can be seen holding his guitar in Party Room 3, though he does not appear to carry it elsewhere.
