Unhatched Mr. Chilly

Source
This companion was mailed to you from Breanni soon after switching your account to a Battle.net account. The first ones were mailed to players on Oct. 15, 2009, three days after Blizzard announced that all WoW accounts would be converted to Battle.net accounts on Nov. 11, 2009.

Mr. Chilly was sent as a thank-you gift to all WoW account owners who voluntarily convert their accounts early. It was only available from Oct. 15 to Nov. 10, 2009.

Trivia
For some reason, probably an error in the skin, Mr. Chilly's eyes glow in the dark.
