As the wolf finishes licking your foot clean you give your head a good yank. The latex gives way and your head whips out of the hole, something that's apparently too much for the wolf, who whimpers in pain the second your head leaves its body and jumps out the window to get away from you. Looks like you showed it who's boss!
Or, you know, maybe you didn't. Yes, it ran away, but it left a big chunk of purple on your head. You can feel the slight extra weight, and even worse, you can SEE the large canine muzzle that now adorns your face. You raise your hands to check it, and feel your long wolf ears, your sharp wolf teeth, your... er... wolfish wolf nose, all made of that strange latex and all very similar to the face of the wolf you just fought off. Everything on it works too: every scent is magnificently amplified, every sound crisp and clear, even your sight seems to have improved. Still, nice as the improved senses may be, you know you can't live with this.
Then again, you could always look at the bright side. At least your foot is normal now, so you're kinda symmetrical.
