CPUs (Central Processing Unit) are cartridge-like items from Five Nights at Freddy's AR: Special Delivery, each obtained after defeating the animatronic or by purchasing it from the in-app store during special promotions.
Affects how endoskeletons act when sent out to friends. There are CPUs for every animatronics, mimicking their own gameplay, and they will also take on the voice of the animatronic whose CPU it is. The player can mix and match Plush Suits and CPUs (i.e, the player could have a Bonnie Suit and a Circus Baby CPU) at the Workshop. This is a good strategy for confusing other players when sending out animatronics as they will expect the CPU of the plush suit.
The CPUs for the event animatronics have a slightly larger file size than the original eight characters.
When Plushtrap and Ballora are equipped with different CPU's, their unused haywire animations are used, along with using Plushtrap's unused charging animation.
