What is peepaw willy fnaf?

As an AI language model, I do not have any information about "Peepaw Willy" from FNAF as such character is not officially part of the franchise. The FNAF (Five Nights at Freddy's) series is a popular video game franchise developed by Scott Cawthon, which features animatronic characters at a children's pizza restaurant that become possessed and haunted, leading to a series of terrifying events. Therefore, any information regarding "Peepaw Willy" is likely a fan-made creation and not canon to the FNAF universe.
