Alolan Exeggutor was added to Pokemon GO in late May, with its event wrapping up by early June. The Pokemon disappeared at the time, but has since returned. Alolan Exeggutor can be found freely roaming in the wild.
Some Pokemon GO players are saying that Alolan forms with regular Kanto pre-evolutions can be seen in the wild, hence this creature’s return. Other Alola variants are hidden inside Pokemon Eggs, but since fully-evolved Pokemon don’t hatch from Eggs, they could be out in the wild instead.
