Moon Cactus

This would be a new type of cactus that generates in the desert biome. Its based off of real life plant, and have a design similar to it. Unlike the plant though, in the daytime its bulb would be hidden. In the night however, the bulb would come out of the plant and produce a small amount of light. This bulb would come in many different colors, including red, pink, orange and yellow. If you mine the moon cactus and smelt it in a furnace, then it will turn into a dye that corresponds with its bulb color
