Karate Tortoise Mask

It comes out of Goodie Bags, so Halloween is the only time to look. Three pieces out of one random source means a fair number of bags before the outfit is complete, and there is no shop or recipe to fill the gaps if the event ends early on you.

All three pieces are cosmetic and go in the social slots. Male and female characters get the same art here, so this is one of the few outfits where the body type you picked at creation changes nothing about the result.

It is Leonardo from the Teenage Mutant Ninja Turtles, blue mask included. The other three turtles never got outfits of their own, so four players cannot dress as the whole team.
