In Pokémon Yellow, it can be found in Routes 12, 13, 14, 15, 24 and 25, while in Pokémon Red it can additionally be found in Routes 5, 6 and 7. With the coming of dawn, the cycle repeats It then proceeds to bathe itself in the moonlight and grow, as well as wander around as far as 1,000 feet (approximately 300 metres) scattering its seeds to propagate the species. It extracts itself from the ground, and its extremities change back into the shape of legs. Once nightfall comes, exposure to moonlight causes Oddish to become much more active. This mirrors the behavior of the legendary mandrake in a similar situation, although it seems that Oddish's squeaks do not have the same dire consequences as a mandrake's. If anyone pulls at Oddish's leaves and tries to uproot it while it is buried underground, Oddish will react by shrieking in a cute, high-pitched voice. While buried, Oddish nourishes itself by absorbing nutrients from the soil using its feet, which are said to temporarily change into a root-like structure for this purpose. In this way it disguises itself as a plant, misdirecting its carnivorous diurnal predators. During the day, Oddish avoids the sun's heat and brightness by burying itself into the earth, leaving only the leaves on top of its head visible above ground. Oddish is a nocturnal Pokémon, using moonlight rather than the sun's rays for photosynthesis. On top of its head grows a large clump of 5 long green leaves. Its body is blue, purple or black with two small feet and red eyes.
Oddish looks like a small animated onion/turnip plant.
