Leslie as both a baby mountain troll and a juvenile snow troll. To illustrate the differences between two closely-residing varieties of troll, I guess? Mountain (or rock) trolls start out cute as hell and get steadily huger and uglier. As they reach adulthood, they begin to form rocky calcified growth along their shoulders and back and can grow to be hundreds of feet tall. They are always ridiculously slow-witted and eat absolutely everything. Snow trolls, in contrast live in unreachable mountain peaks and are highly intelligent, very culturally rich. They only grow to be about ten feet tall and live as monks and healers.
