Exeggutor is a tall, bipedal Pokémon that resembles a coconut tree or palm tree. Its body and legs are light brown with thin black rings and its legs are thick with two-toed feet. There is a light yellow paw pad on each foot's underside. It has thin, green leaves sprouting from the top of its body. Exeggutor has three round, light yellow heads that resemble coconuts, each with different facial expressions.

Exeggutor's heads think independently and don't appear interested in one another, so it makes a lot of noise as each head speaks its mind. They still appear to get along, though, for they never squabble amongst themselves. If all the heads want to go in a different direction, its body is unable to move. They are able to communicate telepathically as well and sometimes use it to come to a joint decision. It uses psychic powers to fight, and since all three heads are capable its power is tripled. If one of these heads grows too large, it falls off and groups together with others to become an Exeggcute. In the anime, Exeggutor also has been seen in groups of its own kind, meaning that it is not a solitary Pokémon. Exeggutor has been referred to as "The Walking Tropical Rainforest" or "The Walking Jungle". It can be sluggish during cloudy days due to the lack of sunlight. Being the result of an evolution via Evolution stone, Exeggutor is rarely found in the wild, though they can be found in forests and jungles.

Forms
Exeggutor has a regional form: Alolan Exeggutor.

Due to the abundance of sunlight in the Alola region, the Exeggutor that live there grow over five times taller than those in other regions. The region is considered to be the best environment for Alolan Exeggutor. Alolan Exeggutor's neck is thinner and much longer, causing it to more closely resemble a coconut tree or tropical palm tree than its Kantonian counterpart, which resembles the shorter desert palm. It has a long, tapering tail with two leaves and a fourth light green head on the tip.

This extra head can also act on its own and defend the rear. The tail can use weak telepathy to scan the surrounding area. Its long neck can be used as a whip to attack enemies with its hard head. However, its neck can also be a weak point, as it will become dizzy swinging it around. Its increased height reduced its need for a psychic defense and has instead awakened its draconic powers, resulting in its psychic powers becoming weaker.

Ancient carvings and murals depict this Pokémon. Alolan Exeggutor is considered the pride of the Alola region by its natives. Alolans take pride in its appearance, claiming this is what Exeggutor ought to look like. Its extra height makes it the tallest and heaviest Grass-type. Alolan Exeggutor can be found on Exeggutor Island, a former trial site in Alola, which is not only shaped like an Exeggutor, but contains many wild Exeggutor, giving the island its name. They can also be found in the Coastal Biome of Blueberry Academy's Terarium, where Alola's island life is simulated.
