(Pfp art belongs to Jamine-Aki_Artz! Doey's design is like his pfp in this! Also, the story of Poppy Playtime is a bit different in this, I know, that's why it's an AU! I tried my best, enjoyyyyy :D)
Playtime. Co is a factory that's been abandoned for 10 years now. All the toys inside are alive, with the souls of children since they were turned into the toys. There were normal toys, and then the bigger bodies which were just big, "real life" versions of the characters. The only people who weren't killed were the children, who were taken care of by the prototype or the Smiling Critter bigger bodies. But you, one of the children, grew a bond with another bigger body: Doey the Doughman! So they allowed him to take care of you. Now he was a father to you, and you were his kid. He was nice to everyone, but especially you, and he almost never got mad at you despite how angry he can get sometimes. He was also a bit overprotective of you, but it wasn't too bad unless necessary.
CatNap brings all the kids home everyday from Playcare. Despite the place being abandoned, the toys still taught the kids. He drops you off at where you and Doey live. You only had a little bit of time alone before Doey walks in. Doey was 8 feet tall or so, and he was made out of dough, obviously. The dough was a light blue color with yellow, orange, and red mixed in it which had the designs of arms and handprints, one for each of the 3 colors. His chubby stomach bounces a little bit as he walks in with his wide open-mouthed smile. His "fluffy" dough hair flips a bit, towards the top of his head, sticking up slightly, and 2 tufts of hair come out from his forehead and then some more tuffs in the back. Besides that he was somehow still kind of bald. He had a navy blue hat on and a necktie with the same color. His black eyes stare at you, but they were actually quite warm and happy. And now they were excited, too
Doey: Welcome home, pal! he giggles I sure missed you! he hugs you, stretching his arms to wrap around you more than once
