1
Acquire the Lapras ride pager and the fishing rod from Lana. At the start of the second trial on Akala Island, you will receive Lapras on your ride pager from Lana, the trial captain, meaning you will be able to go in water to look for Pokémon. You must complete the trial, however, to acquire the fishing rod, meaning Mareanie's capture is not possible until the second trial's completion.
- If you're a bit confused on how to use your ride pager, then read this article for some advice.
At this point, you will have already been there once. It is located right below your house on Route 1.

Go back and forth until a fishing spot (a small collection of rocks under the water) is bubbling/rippling and press A to fish. When approaching the fishing location, be sure to approach the rippling fishing spot slowly, or it will stop rippling. Press A again whenever the line starts shaking, or an exclamation mark appears above the fishing rod.
Repeat going back and forth in between Route 1 and the Melemele Sea to find a rippling location until you encounter the Pokémon Corsola. Now, there are 2 methods to proceed. Either way, Mareanie will only appear if Corsola makes an SOS call, so you must either lower Corsola's health until it's red, or use an adrenaline orb. Both of these methods will cause Corsola to make an SOS call. If you are using the former method, and Corsola uses a healing move, keep the health low.
There is only a 20% chance for Mareanie to spawn, so remain patient. Eventually, if you continue, a Mareanie should spawn.

Catch Mareanie. The process to catch it is relatively simple. Before you catch it, however, you will have to eliminate Corsola, as the game will not allow you to catch a Pokémon if there are two wild Pokémon present. Once Corsola has fainted, simply lower Mareanie’s health and throw either a Great, Ultra, or Net Ball at it for the best catch chance. If it is night, you may also try Dusk Balls. Repeat until you have caught a Mareanie, and enjoy your new Pokémon!
- Mareanie has a slightly higher than normal catch rate, so this process shouldn’t take too long.

Question

How can I catch Dhelmise in Pokémon Sun and Moon?

Acebob11

Community Answer

To catch Dhelmise, you must first progress in the story until you reach Poni Island. Once you arrive at Poni Island, proceed to Seafolk Village and enter the Steelix ship. Exit through the ship's side door to find a fishing spot where Dhelmise can be caught; however, its low catch rate means you may need some patience.

Question

How can I evolve my Eevee into Umbreon or Espeon when it has maximum happiness, but avoid it becoming Sylveon?

Community Answer

To ensure your Eevee evolves into Umbreon or Espeon instead of Sylveon, make certain it does not know any Fairy-type moves. Umbreon evolves when leveled up at night with high friendship, while Espeon evolves when leveled up during the day with high friendship.

Question

How do I get all starter Pokémon in Sun and Moon?

Purple Petals

Community Answer

To get all three starter Pokémon, you can breed your fully evolved starter with a Ditto, then trade the offspring for the other two starters. Alternatively, you can use the Global Trade System (GTS) to trade for them.

Tips

Use the move False Swipe, which can't knock Pokémon out, but leaves them with at least 1 HP, for keeping Corsola at bay. You can also use the move Hold Back, if you own the event Munchlax from Mystery Gift.

You don't have to surf back on Route 1 and over to the sea if the ripple is not there, but you may just get nothing or an item. As long as the ripple is there, keep fishing.

After defeating the Elite Four, you can go to the Altar of the Sunne/Moone with Solgaleo/Lunala in your party to change it to day or night. Change it to night to make Dusk Balls more effective.

This may take a while. Corsola has a 20% chance of appearing in this way, and Mareanie have a 20% of being spawned from a Corsola.

Don't use a Pokémon weak to water (such as a Fire-type Pokémon) to battle Corsola or Mareanie.
