The Pet Arctic Fox is a members-only land pet. It was released on January 5, 2017, and is sold at the "Choose a Pet" menu as well as the Diamond Shop.
The Pet Arctic Fox has a wide lemon-shaped head, a bushy tail, and stubby legs. Its colors are brighter than normal, much like the Rare Pet Phantom.
The Pet Arctic Fox has recently been taken out of stores, but you could most likely request for one from someone who can make multiple, as they had bought one when they were still in stores. Estimated value is around 1-2 RIMs, possibly more if the Jammer is desperate.
