Exeggutor (ナッシー, Nasshii) is a Grass/Psychic-type Pokémon introduced in Generation I, and a Grass/Dragon-type introduced in Generation VII; an Alolan Exeggutor takes on the appearance of a tall palm-tree like Pokémon.
Exeggutor is a bizarre plant-like Pokémon. It is the evolved form of Exeggcute. This is done by using a Leaf Stone on an Exeggcute. Exeggutor takes on the appearance of a walking plant with egg-like heads all around the top part.
Its name may be a combination of egg and executor. Despite its huge size, it apparently can dance if one takes the Orange Islands into consideration.
Exeggutor originally came from the tropics. Its heads steadily grow larger from exposure to strong sunlight. It is said that when the heads fall off, they group together to form Exeggcute. Each of Exeggutor’s three heads is thinking different thoughts. The three don’t seem to be very interested in one another. When they work together, Exeggutor’s three heads can put out powerful psychic energy. Cloudy days make this Pokémon sluggish.
