Weregrinch transformation

With most lycanthrope transformations in movies the transformation process is either depicted as scary or painful. But with weregrinch transformations the proccess isn't anything like that except for the first time it happens and that's because it's an affectionate parody of a typical horror movie transformation scene. It usually starts with the person developing grinch-like traits such as glowing yellow eyes, super keen senses, and superhuman agility, stealth and strength as well as a Jack Nicholsonish Cheshire Cat smile and growling a little. Then green fur starts to sprout all over that person's body and his/her fingernails and toenails grow into long, black sharp claws, and they slowly become more and more grinch-like throughout the process. The green fur growth kind of itches at first but he/she gets used to it over time. Then their features become more and more grinch-like as the green fur starts sprouting on their face, they also develop more grinch-like features including bushy eyebrows and a grinch-like muzzle. Unlike with most werecreature transformations where the face pushes out and becomes a snout, with weregrinch transformations the person's nose turns black and then moves upward because a grinch's nose is a lot higher up on the face than a human's is. And their hair grows longer and longer, they then develop pointed ears and small vampire-like fangs. When the final part of a weregrinch transformation takes place, they become more grinch-like as their hair grows into a mane while the grinch-like muzzle finishes developing and when the transformation is complete they are now a fully transformed weregrinch.
