Hallowe'en pets and Elvis

So, a few days I bought a Black Cat pet from the Hallowe'en vendor and it's pretty cool looking. It's a nice Hallowe'en themed pet to go along with the 'everyday' pets that have a hallowe'en vibe to them: the Black Spider, krokomummy, ghoul, the assorted ghosts and the Wraith.

But I think KI missed an important part of Hallowe'en: Costumes. I know, we can dress our wizards up a bit. Where are the pets wearing costumes? I'll leave the possibilities up to you, guys.

But where, oh where, is the Ninja Pig dressed as Fat Elvis?
