User blog:Panchamp98/You know, something I wanted to know about your favorite scary Pokemon...

What is it? Mines obvious, PHANATUMP! The PokeDex entry is literally THIS!:

X version:  These Pokémon are created when spirits possess rotten tree stumps. They prefer to live in abandoned                      forests.

Y version (THE CREEPIER VERSION!):  According to old tales, these Pokémon are stumps possessed by the spirits                                                           of children who died while lost in the forest.
