Underwater Area
From Poliwager Wiki
The Underwater Area is an area on Poliwager Adoptables where you can go for a dive to find Pearls or other Valuable Items. You will need to purchase HM08 Dive from the Poké Mart before you can go here. Every time you dive in the Underwater Area you will have to wait one hour before you can dive again.
Kyogre
If you have collected a total of 100 Pearls, you may buy a Blue Orb that can be used to summon Kyorge.
Trivia
- Many people throw away empty bottles here which causes some Pokémon to get trapped inside.
