Shades is a Dare Gremlin and likes challenging Button. He rides on Heat. He loves telling Spool that Button likes when people get insulted, and so Spool insults Pink, and Pink chases button until they run into Thimble who is having an angry rage. Then Shades walks off laughing, getting the attention of Loop. If you have read the page of everyone in the S.O.E., this should be getting familiar.
Weirdly, he is also a Friend Gremlin.
