T.R.O.L.S.

Creature brain storm thread here inspired by the Two to the head thread: a T.R.O.L.S. is the alphabet soup acrostic assigned to a creature discovered by the scout service on planet X. It stands for Total Regenetative Ongoing Laceration stitching. Now the creature should not look like a fantasy troll but but I'm opening the floor for ideas on what it might look like, if it should be intelligent, capabilities, ecology, biology etc. Even looking for better word to use in the TROLL acrostic.
