The Elf Costume is a retired costume from the November 2006 Account Upgrades. Put this costume on certain marapets and it will make it turn into an elf. You know about Buddy from the Elf movie? Well, like him, Elf pets are white and pink with a green cap, collar, green clogs, and a red Colonialism era suit. An Elf pet is based on the type of humanoid supernatural being in German mythology and folklore. The new ones are seen carrying brown sacks and holding candy canes, showing us that they're Santa's helpers.
