Gorgeous Christmassy cartoon for young children?

[YunoYurbubson]

I was thinking of doing a Christmas pyjama party for my 2 and 4yo with a film and warm milk.

Can anyone recommend a gorgeous, beautiful animation? Something Christmassy? I love 'Twas The Night Before Christmas' story - and on IMDB it seems as though lots of screen versions have been done but I don't know if any of them are any good.

Suggestions?

DS and I snuggled down and watched The Snowman last year (he was 3.5). It was lovely, although he was a little sad at the end when the snowman melted.

The Grinch?

robbie the reindeer - ds loves anything by ardman animation - shaun the sheep, timmy etc!

father christmas - another raymond briggs animation

i'd watch anything by pixar although not terribly christmassy

Barbie Swan lake ? or Nutcracker ?
