Paras

Paras appeared in 1996 video game called Pokémon Red & Green. Paras is a Mushroom Pokémon. When Paras eats, it's mostly just feeding the mushrooms that grow on its back. These mushrooms known as tochukaso, can be picked, dried, and ground into a powder for use in medicine.

Paras is an orange, insectoid creature resembling the nymph stage of a cicada. Its ovoid body is segmented, and it has three pairs of legs. The foremost pair of legs is the largest and has sharp claws at the tips. There are five specks on its forehead and three teeth on either side of its mouth. It has circular eyes with large pupils.

Red-and-yellow mushrooms known as tochukaso grow on this Pokémon's back. The mushrooms can be removed at any time and grow from spores that are doused on this Pokémon's back at birth by the mushroom on its mother's back. Tochukaso are parasitic in nature, drawing their nutrients from the host Paras's body in order to grow and exerting some command over the Pokémon's actions. For example, Paras drains nutrients from tree roots due to commands from the mushrooms. The mushrooms are also popular among collectors and have medicinal uses, usually involving extended life. The mushrooms are also the source of its former signature move, Spore.

The anime has shown that Paras can often be found in caves. However, it can also thrive in damp forests. In the Alola region, the mushrooms on its back do not grow well. This thought to be from a lack of moisture or nutrients.
