The least common, in addition with age, would make Ratthe rarest pet in the game and possibly the rarest item. Some staff members have it, but there are only three active players (not staff) who own it. It was a reward from the Take Down quest but was removed in 2008. The pet appealed to few players and later became a very hyped pet for knowledgeable players. Dark Wolf is extremely old, however, many players from 2008 still own it. The Platinum Dragon is a fairly unique pet, but it is still available to players with the Founder badge, which is a very numerous amount.
