Fun Hill

Exploration Stage: Miracle Fair
From: Professor
Description: Catch him, catch him! That elf in the red cap went down the hill in a runnerless sled! It’s an integral part of my ingenious snow machine. Can you persuade the elf to return it? In the meantime, I’ll look for other parts of my invention.
Completed: I see you didn’t return empty-handed. You have the runnerless sled. Thanks for your help! I need it to grind and fluff the fresh snow produced by the snow machine. How did you get the elf to return my part?
