Furret closely resembles a ferret. It has long, dark brown/tan fur, 7 rings on its body, no visible nose, and four brown, whisker-like marks on its cheeks.
Furret can have one of two Abilities, Run Away or Keen Eye. Run Away is an Ability that guarantees escaping from a random encounter. Keen Eye will prevent accuracy loss from this Pokémon. Furret are also very quick, and can quickly escape or move through very narrow spaces. It also loves chasing Rattata.
Furret has a "mask", similar to most ferrets, in Pokémon Gold and Silver but no longer appear with it in later games.
Furrets have a similar appearance to the Hoenn region's Linoone, and are also the evolved form of one of the first seen Normal-Type Pokémon, just as Linoone is.
Furret has little appearance in the anime, except for once in the Silver Conference, once in the Hoenn League, and a short appearance in the Sinnoh Saga where it was seen on a stretcher being carted off into surgery.
Furret appears in Pokémon 4Ever when a Furret led Ash and his friends to the Lake of Life so they could heal Celebi.
In episode 267, Furret is called a Ground-type Pokémon by Brock.
