Chucklehead

Chucklehead is a Goblin who runs the Candy Market in Loomlurch. Fey magic has reshaped his head into a large toffee apple. At some point, a maggot crawled in and began to eat at his head from the inside. It ate away some of the rot it found, he believes, causing him to have changed from a selfish and uncaring person into someone with empathy towards others. He insists that the maggot talks to him, and he often can be found speaking aloud to it in turn. Although he's sure the maggot will ultimately kill him by eating his whole head, he doesn't want it removed or killed, as he fears he'll go back to being the terrible person he was.
Chucklehead has a great fondness for Mishka, one of the kids that Skabatha Nightshade kidnapped and put to work in her toy factory. Mishka is the only child who doesn't mock how he looks, and he feels protective towards her.
