I have a black with a white, kinda frosty looking, belly named Sullivan, and a also black with a red orange under belly named Rudy. They are brothers. I found Sullivan slaying dimorphodons by the tropical and winter boarder on the island, and I after I tamed Sully and brought him home I saw Rudy stop’n around by my raft. Apparently, he told me that he was chased off the cliff by a theri and was “admiring” my meat stack in my boat. I chased him around for awhile then he killed a Sarco and then I knocked him and then used his tale ad a catwalk for a little, then BOOOM two amazing rexes I will fight to the end for!
