Bulral have the frame of a wooly mammoth, but are entirely covered with white fur like a polar bear. Instead of a single trunk with long tusks, Bulral have no tusks and four trunks surrounding their mouth, and each trunk is barbed with small thorns. They are fierce and solitary hunters who have a bizarre friendship with the hotheads.
Teenagers who run away from home to live in the wilderness may become feral. As they become more and more feral, they gain some supernatural powers (a la Peter Pan - ability to fly, things they imagine come true - possibly quite powerful), but at the expense of their humanity and ability to speak, comprehend complex subjects, etc. Maybe they have a leader: the most feral of them all.
A regression into a fantasy childlike state.
