Moonlight Moth value in Adopt Me

Sticky pet: the number looks fine, yet few players want it. The supply is there, but no one queues up for it. If you get an offer, double-check what comes back before you accept.

The Galactic Pass event is over, so the only way to get one now is trading. It's listed as rare, but that doesn't make the trades come any faster.

A normal FR is worth noticeably more than a normal with no potions, so don't let a plain one go cheap. A Neon goes for less than the four normals it takes to make it, so keeping normals beats building a Neon.

Value-wise it lines up with St Bernard and Partridge, both retired too. You won't lose out by taking it as an add on a pet that actually moves.
