No, I think he's an ENFJ.
He firstly loves interacting with his elves and Mrs Claus, and definetly looks at his surroundings. E.
He does something unique and tries to help change the world to being more giving, plus his sleigh is pretty creative. N.
He is obviously very generous. F.
He judges who is naughty and nice, and he keeps a routine and is very organized to deliver presents. J
Fun! I put in a vote for ENFP, just to make a different argument. I picked that because of the image he always represented to me: the everlasting joy of a curious, creative child, doing what he loves and happy to be quite a character in the process. I would say either that or ENFJ.
