I always thought Finn was more boxy while Fionna does have some meat on her (truth be told, her figure reminds me a lot of mine), she's more curvy. I agree though, their shapes are meant to represent the style of the show.
Fionna is a genderbent version of Finn. Fionna is chubby because Finn is chubby. It's pretty hard to miss all the shots with Finn's gut pretty much being in plain sight, and when he's shirtless, lovehandles are clearly visible.
It all depends on the artist that draws him in the episode too. Seeing how they tend to draw characters differently. For example, PB.
Yeah, I don't get it. Finn is pudgy with noodle arms but people decide to portray him as thin and covered in lean muscle for whatever reason. This show also has more cool chubby characters, like Flame Princess, but my guess is that if I tried to search fan art of her, I'd find her skinny as well. -_-
"cute" chubby??! Theres only 2 types of chubby ; Regular Chubby , and fat chubby :L fionna is neather , sure her legs may be slightly chubby but the rest of her body isnt :L and finn is basicaly a tooth pick ._.
Who are you to say that there's only two kinds of chubby, there are more than two kinds of body types FYI, Fionna's just got a belly and slightly big legs. She's not fat. You can actually see her belly hang a bit in a few scenes. Don't try and say that the person who created the character is wrong. Nat made Fionna a cute kind of chubby, therefore Fionna is officially chubby cute. Finn isn't just a toothpick, in case you haven't noticed, he's got lovehandles and a gut.
