Pep is a prototype penguin animatronic who is part of a west-line of animatronics. Although he is young and innocent, he is quite intelligent and adaptive. If he is a success, plans will be made of installing a similar AI in Freddy, Foxy, and Balloon Boy. The only thing known about Pep's creator is that he was wearing purple clothing. He recalls being made and tested in the foundry factory near Chicago, Illinois. He is friends with Daken and Balloon Boy 2.0.
