Sled

The sled is one of the two newly-added vehicles in the new update, "Faster!". It allows the player to zoom across the winter biome faster than ever before, and is useful for escaping some mobs. It can only be used in the winter biome.

It is a much earlier-game item than it's counterpart, boat, and you can get all of the needed resources in the forest biome. It is also helpful if you are trying to get a dragon heart, as you can go to and from the dragon cave much quicker.
