Lime Kelp

The Lime Kelp is a dye material and type of plant that is found under any liquid (most commonly underwater) in the Underground and Cavern layers. It is most common in the Snow biome, and spawns very rarely in the regular underground and cavern layers. Lime Kelp has a tendency to blend in with the background, so locating them may prove difficult. It can only be harvested with a Pickaxe. Its sole purpose is to make Lime Dye.

Tips

 * The most efficient way to farm Lime Kelp is to explore a map's underground snow biome, then use the world map to spot dark green isolated pixels in the water bodies. Mousing over a Lime Kelp on the world map will show its name on the tooltip. Since the world map updates with a live feed of each explored area, lime kelps will be easier to spot. This works on every biome, however the kelps are more commonly found in a snow underground biome. They are also easier to spot on the map due to the white / blue background.
