Formerly a prosperous fishing town, the Coral Ward dwindled in prosperity as more and more toxins were emptied into the water, eventually leaving it a near-ghost town. The water is so polluted that most Pokémon can't even touch it.
On the northernmost dock of the town is a mysterious woman mulling over how to rescue an Popplio stranded in the toxic water. Cain shows up and introduces the player to the woman, named Amaria, and takes it upon himself to rescue the Popplio with his Grimer, battling the player to help soothe its jitters.
After obtaining the HMs Surf and Dive, the player can obtain the Coral Key (and an Electirizer as a bonus) hidden in a secret room reached by using dive behind the southern lighthouse (view picture below). The key unlocks the door to the northern lighthouse nearby. Using dive within the northern lighthouse leads the player to an encounter with a Popplio being harassed by a Huntail and Gorebyss. Defeat the two Pokemon to collect Popplio, as well as the nearby TM68 Giga Impact.

In the house to the left of the Pokémon Center, a young boy frets over a Skitty that has taken a rough fall. He's certain he can help it himself, even without the Pokémon Center, but his grandmother knows he needs something like an Ultra Potion to help. If the player has one in their bag, they can give it to the boy and let him heal Skitty himself. He still worries about what would happen if he just let it go out into the wild again, so, exasperated, his grandmother asks if the player would be willing to look after it for them. The Skitty will know one of these moves: Wish, Sucker Punch or Zen Headbutt.
After encountering the Spoink in the Obsidia Ward on a clear day, the Spoink will run to the storage unit southwest of Pokémon Center and hide in one of the boxes.
Please store the elderly in the proper storage unitEdit
After obtaining the Warehouse Key from the Obsidia Ward, the lower storage unit by the docks can be opened, revealing the true Day Care Couple. They give the player their heartfelt thanks and tell them they are welcome at their Day Care any time.
The Warehouse Key also unlocks the storage unit south of the Pokémon Center. After the Day Care Couple have been released, a Team Meteor Grunt will appear, counting up the Pokémon stolen from the Day Care. The Grunt notices the player and complains about their constant interference, but chooses to escape rather than confront the player, their task completed. With the Grunt gone, the player can make their way to the back of the storage unit, where a lost Happiny has ended up.
