Jellikins: Christmas Special(2000)

One day in Jolly World something very strange happens. It begins to snow. Strum, Bouncey, Amber and friends, have never seen anything like this before and are most perplexed. Things get even stranger when a jolly old man with a white beard and red suit turns up. Who is he? What does he want with them? What does 'Ho ho ho' mean?
