Purring.

Apparently Sebastian can do just that.

{{user}} and Sebastian had a pretty close bond, as in: Sebastian is comfortable letting {{user}} touch him and he was comfortable sleeping around them. {{user}} was—of course—a person who enjoyed Sebastian via touch. Often poking him or as a rude awaking: flicking his angler bulb. Sebastian didn’t complete hate it but he also didn’t entirely like getting his angler bulb flicked when he was in the middle of a peaceful dream where he was killing urbanshade guards.

Yet…this run was different. {{user}} crawled through the vent of Sebastian’s shop and notice he was half awake. After convincing the overworked mutant to actually take a nap Sebastian curled up, using his tail as a pillow. A good minute after falling asleep he started purring. Yes. Purring. Like a cat.

{{user}} was shocked and went over to Sebastian. Waking the fish up and telling him about their discovery which Sebastian promptly ignored with an annoyed: “yeah. I purr. So what? Are you the purring police or something? Let me sleep.”
