lwo oddish - Oddish by GPjube

Oddish searches for fertile, nutrient-rich soil, then plants itself. During the daytime, while it is planted, its feet are thought to change shape and become similar to the roots of trees. Oddish grows by absorbing moonlight, and the more fertile the soil, the glossier its leaves become. As only its leaves are exposed aboveground when it is buried into the soil, in order to avoid detection by enemies, it is said to look like a clump of weeds. It is also said to scream loudly if anyone tries to yank it out. Oddish is nocturnal, and awakes upon being exposed to moonlight. Upon awakening, it roams about actively, walking nearly 1,000 feet and scattering its seeds to create more Oddish.
