Giant Tattoo Mutant
Scientific name: Mutatur threicae
Encounter level: When you least expect it (Improbable Event)
Special abilities: Has an eight pack. Absolutely shredded. Interacts with tattoos… somehow.
Drops: No meat, all EXP.
The Mighty Magpie's uglier, but far more polite, cousin.
Another persistent threat from Season 1, this three-headed monster has a devastating attack level. Unless you are strong and healed, your best bet is to run for your fucking life. Unlike the magpie, you're more likely to hear the Tattoo Mutant stomping through the trees towards you, giving you a chance to run away. If you decide to fight it, expect to take major damage (and possibly suffer charm or cig loss on a defeat). But if you do manage to kill it, the ridiculous amount of XP it awards is usually enough for a level and a half.
The Giant Tattoo Mutant is either harmed by or attracted by Tattoos, but no one can remember which while editing this wiki page.1) If you'd like to test it for yourself and put this argument to rest, try the tattoo parlor in Improbable Central. Look for the Mutant in the jungle surrounding any outpost.
