The Unbeatable Squirrel Girl! (Patreon)

In her new series, Squirrel Girl goes to college in her civilian identity. Since she has an actual squirrel tail, her solution is to stuff that bushy sucker down the back of her pants so she can pass for a normal person with a "conspicuously large and conspicuously awesome butt." It's a pretty good series, you should be reading it! This might not even really count as fatness since it's, y'know, just a tail, so, uh, she also gained the freshman fifteen, how about that?
