Brooklet Hill

The trial begins as soon as the player walks through the trial gates (which are located immediately before the Totem's Den); however, the player can leave at any time with no impact on the trial, since the trial only includes the battle with the Totem Pokémon.

In this trial, the player must investigate the mysterious rippling water in the middle of the Totem's Den and defeat the Totem Pokémon. In the battle with Totem Wishiwashi, it will call Wishiwashi on its first turn, and call Alomomola if its HP is below half (if the ally Wishiwashi has been defeated). If its HP drops below approximately 2/3 before it has a chance to call an ally, it will call Alomomola first, then call Wishiwashi at the first opportunity after Alomomola has fainted. Once an ally is defeated, Totem Wishiwashi cannot call it again.

After defeating the Totem Pokémon, the game cuts to Lana and the player talking on the shore. Lana gives the player a Waterium Z as a reward, as well as the Fishing Rod and ten Dive Balls. After completing the trial, wild Pokémon will appear in the Totem's Den.

Unlike normal Wishiwashi, Totem Wishiwashi begins battle already in School Form. However, like normal Wishiwashi, if its HP drops below 25%, it will revert to Solo Form. The battle begins with rain in effect.

The trial begins as soon as the player walks through the trial gates (which are located west of the first lake); however, the player can leave at any time with no impact on the trial.

In this trial, Lana requests that the player drive the Wishiwashi in Brooklet Hill's pools downstream in order to draw out the Totem Pokémon. The first lake is not part of the trial site. In both lakes within the trial site, each contains two water splashes, one containing a Dewpider and the other containing a Wishiwashi; to progress the trial, the player only needs to defeat the Wishiwashi (the Dewpider's water splashes disappear once the player completes the trial if they have not been defeated). Lana will not allow the player to proceed further south until they have defeated the Wishiwashi. Once the player sends both Wishiwashi downstream, it will start raining in all of Brooklet Hill, causing it to rain in all battles conducted there until the trial is complete.

Unlike other non-Totem SOS Battles, the initially encountered trial Pokémon in the third lake will successfully call for help every turn as long as it does not already have an ally, even if it has a status condition; the Pokémon called as allies will not themselves call for help. The Pokémon encountered in the second lake do not call for help.

When the player enters the Totem's Den, they will see a small water splash in the center of the den, which Lana tells them is the Totem Pokémon. When initiating the battle with the Totem Pokémon, the overworld rain gets stronger throughout the whole area (although the regular rain condition still occurs in battle), remaining in effect until the player defeats the Totem Pokémon even if the player loses to it. In the battle with Totem Araquanid, it will call Dewpider on its first turn, and call Masquerain if its HP is below half (if the ally Dewpider has been defeated). If its HP drops below approximately 2/3 before it has a chance to call an ally, it will call Masquerain first, then call Dewpider at the first opportunity after Masquerain has fainted. Once an ally is defeated, Totem Araquanid cannot call it again.

After defeating the Totem Pokémon, the game cuts to Lana and the player talking on the shore. Lana gives the player a Waterium Z as a reward, as well as the Fishing Rod and ten Dive Balls. After completing the trial, wild Pokémon will appear in the Brooklet Hill trial site and Totem's Den.

Sometimes when fishing, an item will be reeled in instead of a Pokémon.

Brooklet Hill first appeared in True Identity and the Totem Pokémon of Brooklet Hill. Lana took Sun there so that the latter could battle the Totem Pokémon causing havoc in the area.

There, Sun met and befriended a wild Wishiwashi that he decided to nickname Quarter. Sun asked Quarter to lead him to where the Totem was, only to waste several hours being led to the wrong Pokémon. Angered by this, Sun's Dollar tried to attack Quarter, causing it to get scared and flee. Shortly after, a school of Wishiwashi begun to circle around Sun before leaping out of the water in their School Form, revealing to Sun that Quarter and the other Wishiwashi were the Totem the entire time.

With the help of Cent, Sun battled the Totem Pokémon. By having Cent attack Quarter, the Wishiwashi in control of the School Form, Sun caused the Totem to be reverted back into its component Solo Form Wishiwashi, defeating it and completing the trial. Afterwards, Sun formally added Quarter to his party.
