Will it ever be for sale again?

I bought Nexon for the cloud so I could heal my puppet all the time, then looked at the shop and it wasn't there, and when I checked the nimbus again it said limited time. -_-

Nexon sometimes puts pets back on sale, but no one knows when they will.

Ya more often than not, all good pets are limited time. Check if they are limited time first. The only pet that is good to modern (arguable) standards that isn't limited time is the Warp Imp.

Edit: In fact, Little Hopper just went off sale three days ago.
