collect.pet / Sets / Fabled Foundlings / Frostmop
Frostmop is card 7 of 25 in Fabled Foundlings, a Common with the role of snowball hoarder. Soft-spoken by nature, usually found at a moonlit clearing. Like every collect.pet card, each copy is minted with its own serial number the moment it is pulled, and a foil version with a gilded legend treatment turns up about once in 250 cards.
Pull Frostmop from the free daily pack or a Fabled Foundlings set pack, or buy a copy on the player market.
