This pokemon papercraft is Phantump (Bokurei), a dual-type Ghost/Grass Pokémon, based on the anime / game Pokemon, the paper model was created by aquametal. Phantump evolves into Trevenant when traded. There are two scales for this paper model: 13cm in 3 sheets or the small size 10cm in 2 sheets.
Phantump is a spirit possessing a rotten tree stump, and lives in abandoned forests. It is a wispy, grayish black Pokémon. A small tree stump covers its head, with a single, wavy branch situated on either side and extending upward. Each branch has two small, green leaves near its tip. Phantump's red, oval eyes are visible through two holes in the body of the stump. On its body is a pair of tiny, stubby arms and a wispy tuft on top of its head. Its mouth appears to be on the stump itself rather than on Phantump's body.
It is said that in forests where humans seldom tread, the stumps of the very biggest trees become Phantump. People that happen to enter the forest may be led astray by Phantump, as they are capable of imitating the sound of children's voices. [Source: Bulbapedia]
