Was this the final part, where it was going to be a full battle for the whole part, including superpowers? If so Mim, not having any superpowers and not being a warrior, may not fit. Same if I do Mr. Thicknose, he has no powers nor is a warrior. Same with Ducky, Littlefoot, & Petrie, unless there are things for them to do, they are not warriors either, and have no super or magical powers that I know of. The closest that may have that are Mim who seems good with knowing about plants and healing, but that is not magic, making splints, & stuff mainly seen in various movie and tv episodes, and I doubt Mr. Thicknose's having maybe a photographic memory is very super or magical. Assuming he really did mean that he remembered every word of what he heard the farwalkers say about the mysterious beyond.
