Love that character even though she is just a fantasy character inside a cartoon, she is the double rainbow of fan fiction born from incredible loneliness of the Ice-king
Pendleton Ward the creator of this show is one of my favorite cartoonist and I love the message he is trying to put out with the show ... LOVE ! CARE ! FRIENDS ! RIGHTEOUS BUTT-KICKING ! BACON !
Me and my room mate have plans for Fin and Jake cos play but we might do "grown up" Fin and Jake because I just dont have the face for a "13 year old boy" and I dont wanna look like a pedo but I am growing my hair anyway (girlfriends order) so I got the hair nailed down, gone go with classical Fin hair but how do we turn a large bearded man into Jake the dog ?!?! (my Room mate)
Actually I don't understand why but I imagine 'humanisation' of Jake as a adult man. I understand that they're bros with Finn and growing together, but anyway, in my point of view you won't made a mistake if you made Jake as bearded big man Btw according to cartoon Jake already have the kids, so that's means he's mature enough. Also it doesn't looks smooth and neatly, I see Jake as a unkempt manly man (in good meaning of those words). I hope my advice will help you, darling~
Well..Fionna and Finn are both teens actually..13.. But I'm just glad they didn't stereotype her and make her 'model-skinny' and actually gave her some characteristics :] LSP too. I'm sorry but there is too much of "the main chara has to be really skinny or else no one will like them."
