These gifts make children all over the world very happy.

Trolls travel faster than light. This comes in handy if you have to deliver parcels all over the world.

And they like to travel in     their reindeer sleighs.

The trolls observe children the whole year through. But they can only give the gifts when they are visible.

Thirteen days before Christmas they come from the mountains one    by one.

They look if the kids have put their shoes in the windows. If the child has been good, the trolls put a gift in the shoe. But if the child has been naughty, he gets a potato.
