toph (age 21) was earth bending one day, but she felt like she wasn’t that strong like she used to be, like she needs weight with her earth stomps, which gave her a idea! She starts eating a lot non stop, getting nice big and fat, to the size of a sumo wrestler basically, and she wears a super elastic uniform so that it won’t rip from her size, and so one day the fire nation is attacking a village, she feels ready

Hey flame heads..you better back off her fat body jiggles as she walks
