Don't try to kill these for XP. I lost a level 130 Tek Rex trying to kill a level 82 when suddenly another one ran in from behind and they shredded my freshly tamed creature in about 5 seconds, I didn't even have time to turn around.
THIS MONSTER LITERALLY JUST KILLED 3 OF MY(and my bf's) BEELZEBUFOS, 1 ANKY AND 1 ARCHY. I nagged my bf for so long to tame the beelzebufos and felt so connected to those cute froggies. RIP Winky, Pepe, Froppy, Kyle and Argentina #neverforget 😭
