The official Pokémon website has announced that visitors to the 2017 Pokémon World Championships at the Anaheim Convention Center will be able to get an Alolan Exeggutor from August 18th, 2017 until August 20th, 2017.

Get an Alolan Exeggutor!

Anaheim, California is covered with palm trees, but there is one Pokémon that rises above them all—Alolan Exeggutor! You can get an Alolan Exeggutor for your copy of Pokémon Sun or Pokémon Moon by stopping by the Anaheim Convention Center during the 2017 Pokémon World Championships. This Alolan Exeggutor may not be the fiercest Pokémon on your team if you're playing competitively, but its Harvest Ability will prove extremely valuable, and it arrives knowing the unique move Celebrate, which it can only learn through this distribution.

Look for signs at the Pokémon World Championships with directions on how to get Alolan Exeggutor via local wireless. You'll need your own system in the Nintendo 3DS family and a copy of Pokémon Sun or Pokémon Moon to get the Alolan Exeggutor.
