Exeggutor Island (Japanese: ナッシー・アイランドNassy Island) is a small, uninhabited island off the coast of Poni Island, designated as a nature preserve. It is accessible via ferry from Seafolk Village. According to the chief of Seafolk Village, the island was formerly a trial site.
As its name would imply, Exeggutor Island is a small island roughly shaped like an AlolanExeggutor, where many Exeggcute and Alolan Exeggutor live. Some Exeggutor blend in with the palm trees that mark the island and use them as camouflage.
