The Creature's verbosity and general "so done right now" attitude are canon from the original novel. The giant green ragdoll look is . . . probably not? I would have to give it another read, but I think the look of the Creature is fairly undefined in the novel. I'm not even sure the stitches are mentioned! (I'm guessing that someone on here will be able to confirm or refute this claim.) My Creature doesn't look very scary, right? They're supposed to be scary enough that the mere sight of them causes Frankenstein to freak the fuck out. I don't think this Creature is freak-out scary, but in my defense, the canon Frankenstein is a pretty flighty guy. He would probably freak out if a bunny looked at him the wrong way.
