Evil Elf works in the North Pole with Santa Claus. He tries to fool Santa and the other elves. He is always found out and when he is found out, Santa talks to him.
Santa figured out that Evil Elf was evil because he didn’t like working in the workshop. He sent Evil Elf to the stables to help Arthur Elf with the reindeer. He was a lot happier and wasn’t as evil anymore.
