Back when Toy Bonnie was 16 wearing pull-ups got to the point when he would forget about it and Springtrap would have to tell him he needs it changed either before he goes into water or he filled it with pee and there'd be times when nobody reminded him and he'd realize he'd realize he had one one himself like when Toy Bonnie took a bath he forgot to take his pull-up off and he noticed he had it a few minutes into his bath.
