Alola's warm climate and abundant sunlight has allowed the Alolan Exeggutor to grow to a truly fearsome size. Although most of the archipelago's natural trees have been felled for timber, it would be a truly brave person who attempted to raise Alolan Exeggutor for similar purposes, for their deceptively thin necks are as sturdy as the trunks of far thicker trees, but offer these pokemon immense reach with a deadly weapon.
Exeggutor Island is the only island in Alola with no permanent human occupation, but Poni Island's strongest and most courageous trainers occasionally venture there to harvest coconuts for trade. The Exeggutor see the island's trees as their brethren and the coconuts as akin to lost Exeggcute heads, and their heads point in every direction and tower far above the waves. An extensive ritual has developed around a flute and prayers to a nebulous island guardian, but it seems to do more to calm the harvesters' nerves than to calm the Exeggutors' wrath.
Ultimately, Alolan Exeggutor are wild pokemon, and there is only one reliable way to convince a wild pokemon you are worthy of collecting its kin. And for all their size and power, Alolan Exeggutor rarely appreciate an encounter with a well-trained ice pokemon. Most harvesters simply use their pokemon to distract the Exeggutor long enough to gather their coconuts and sail away, although they are not truly safe until their boats are out of reach of Exeggutor's necks, and some have drowned within sight of the shore or even been marooned on the island. Yet the few to defeat and capture Exeggutor have won themselves a mighty pokemon, for no sight in the history of Alolan warfare is more terrifying than a warrior holding a lance while riding on the back of a charging Exeggutor!
