The atmosphere in Iki Town is a lot more lively than before, what with the festival to honor Tapu Koko. Speaking of, you shouldn’t keep the tapu waiting. Make your way towards the staircase to the upper part of the town to encounter Hau and his Pokémon partner. If you’re ready, agree to take part in the festival battle.
Pokémon Trainer Hau
|Popplio (if you picked Rowlet)||7||Water|
|Rowlet (if you picked Litten)||7||Grass/Flying|
|Litten (if you picked Popplio)||7||Fire|
Your rival Hau has picked up a rare Pichu during his way back to town! It’s an Electric type so Popplio users will need to be somewhat cautious. That said, if you’ve been catching a lot of Pokémon (and gaining experience), your Popplio should be strong enough to tank a few of its Thunder Shocks.
Once Pichu is out of the picture, the rest of the battle should be a piece of cake. Don’t hesitate to use the Paralyze Heal you picked up if Pichu somehow paralyzes your Pokémon. Likewise, if your Pokémon are low on health, that’s what Potions are here for! Just go to "Bag", then navigate to the relevant tabs to find the items.
Having shown off your battle prowess to the residents of the town–and Tapu Koko itself–Hala will come over and reward you with the Z-Power Ring . This nifty bracelet lets you use powerful Z-Moves in battle, if you had some Z-Crystals that is… Which is where the island challenge comes in!
Before getting ahead of yourself though, it’s time for the Professor to take you back home to rest.
