Colt is a thimblet with a personality that'd rather fit a smaller creature. He's soft-spoken, quiet and a bit timid, and doesn't like being the center of attention at all. Though they can come off as scared at first, Colt does enjoy the company of others - he's just shy, and nervous when meeting new people. He might not be the best with words, but Colt shows their appreciation of others through actions, and is fiercely loyal to those he considers friends. Colt - and their swarm of moths - moved to Boarstrack Farm when they heard there would be need for a carpenter, and Colt's made himself home helping around with construction work, from renovating the farm to making very nice furniture.

Being a ghost thimblet, Colt used to be a human being before dying and turning into a thimblet. They seem to recall some aspects of their past, but either they can't remember all the details, or then they'd just rather not talk about it. It seems Colt has some regrets about his past life, and is trying his best to become braver.
