Effect Spore
Contact with the Pokémon may inflict poison, sleep, or paralysis on its attacker.
Dry Skin
Restores HP in rain or when hit by Water-type moves. Reduces HP in harsh sunlight, and increases the damage received from Fire-type moves.
The bug is mostly dead, with the mushroom on its back having become the main body. If the mushroom comes off, the bug stops moving.
Its poisonous spores are also used in traditional medicine. Apparently, spores produced in Alola are not of very good quality.
Mushroom-lacking specimens of this Pokémon lie unmoving in the forest, lending credence to the hypothesis that the large mushroom is in control of Parasect’s actions.
