The Treants are a type of Tree Creature in Tiny Tina's Assault on Dragon Keep DLC
When they die they release a bunch of little electric orbs that follow you. They've got little Stumpy versions of themselves that come at you looking adorable, and die, making you feel bad and you don't even know why.
Treants hate Orcs and will attack them on sight
