I havent seen or used the Mangle x Foxy ship in a *LOOOONG TIME* ever since MatPat said Mangles soul is Chicas (Susie's) lost dog. And it was weird since its a kid with a dog. Dam the good memories though it was sooooo popular.
the "Susies dog possessing mangle" isnt canon, its impossible for a dog to posses an animatronic, theres more of a possibility that its based off of her dog but mangle was made before Susies dog went missing. But tbh i dont like the Mangle x foxy ship AT ALL
