Here's a model from Series 4 named Obnoxious. She lives on the Island of Misfits toys and is a long time member of the Fiend Club. She's got an extra slot on the top of her head for her mohawk. I know the model says glueless, and you can just cut and fold and insert the mohawk without glue, but I think it's a good idea to fold it in half then glue it together. But this is your world, so you do what you want.
Short and sweet. Literally. I got more editing to do. Take care!
