Crocus is a bit of a mischief maker and likes to be in everybody's business, usually popping up when people least expect them as a voyeur.  They're hard to get a direct answer out of for most of the residents, and they love to cause a bit of confusion (to this day, nobody really knows what gender Crocus is - only Salem and Crocus know, and they aren't telling).  For all of the tittering chaos they like to be involved in, Crocus is genuinely fond of all their housemates once getting over any initial suspicions (all new residents go through a period of being snooped on, with Crocus reporting whatever they deem important to Salem).  They're the most loyal to Salem, being their servitor, and will defend him to the death.  Crocus is the most fascinated with Lariat and Copernicus.

Fun stuff!  Or at least, that's how they describe it.  They seem incredibly averse to pants, favoring shorts and a unique blouse or skirted top, and usually borrow shoes from Issy.  They're usually not appropriately dressed for the occasion, and they have no issues with it.  They love a good headband.

Snooping on the others and getting entirely in their business, riling up Issy for laughs, and avoiding all possible chores suggested to them.  They spend a lot of time fussing with their hair, and likes to brush it out in Robin's room because it's funny how frazzled he gets seeing a big hairball on his desk for the umpteenth time that week.
