This cow plushie has some minor animations: it chews its cud, swishes its tail, and twitches its ears but it does not wander like a house pet. The maximum scale is rather limited, so it can not be made quite a large as the cows seen in the farm fields Commonlands.
This is one of several plushies available during Brew Day from a quest. See the Brew Day page for a list of quests that may have other plushies or the page for Balin Copperfoot for any that may be purchased with Beer Tokens.
This article refers to events, personae and activities only present in-game during the annual Brew Day celebration, which comes to Norrath each year the week of March 17th.
