Diantump's leaves are translucent and even glimmer in the dark. They prefer to live in caverns and ravines. The regions they live in often grow large clumps of crystals, which they will hide in when scared.
These Pokémon are stumps possessed by the spirits of children who died in the forest. A sudden transformation of Carbink, its pink, glimmering body is said to be the loveliest sight in the whole world.
