Kelp

Kelp is a type of plant block added to Minecraft in the 1.13 - The Update Aquatic.

It was added in the 18w07a snapshot, and it can be planted underwater. Smelting it in a Furnace/Smoker/Campfire yields Dried Kelp. Players can eat dried kelp very fast, faster than other foods. 9 dried kelp can be crafted into a Dried Kelp Block which can be used as a source of fuel.

Wandering Traders will sell kelp in exchange for Emeralds.
