Quote context

[...]

- They brought the little fella to the elf queen, Tanta Kringle.

- A baby! What a splendid idea. He shall live with us and sleep with us, and drink warm cocoa with us.

- What will we call him, Tanta Kringle?

- His license says, Claus.

- Unusual name. However, we shall call him Kris. Kris Kringle!

- Well, those little Kringles took that baby to their hearts.

- Soon as he was old enough, they set up a little school, and taught him all the important things: How to read, and write, and talk, and count stars on a crystal night, and how to make toys.

- Make toys?

- Oh, sure! That was the Kringles' main occupation. They were toymakers. The only problem was there were no children to give them to.

- Remember, Sombertown was on the other side of the Mountain of the Whispering Winds. And the little elves Just couldn't make it past the Winter Warlock.

- So... The toys kind of stacked up some.

- It's really quite sad.
