I also returned my mule to Sandy to buy her 10 marbles.She's not dead...just sleeping.
I blame Pet Food Alpha for reminding me about the Moggy Bonanaza New Years Extravaganza Super Kupofried Special Collector's Edition Contest.
I don't remember what the rewards were, but I won't win one, so I'm not too concerned about it. Well, I'll probably get one of the furniture/BCNM things on my main which will just waste some inventory space (like the marbles are currently).
My mule's Adamantoise is lonely, maybe I'll get a Shadow Lord or something to keep it company?
