How about a sled for the snow biome?
Use some straight branches with curved branches for the runners, a wooden board for the seat and 2 blades for runners to be faster. Use the file on the runners. Use oli on a wool pad for the finishing of the runners. Add a lasso at the end.
The world is flat so you wont go anywhere with it. Thats why you need a strong dog who can pull you around. So feed a dog and combine the sled with the dog. This only works in the snow biome of course. Now you can race each other in the snow biome. The dog wont die this way. And even kids can use the sled.
