Climbing up Oni Mountain, Liko, Roy, Dot, and Friede finally reach the end of the Infernal Pass and arrive at the Crystal Pool at the mountain’s summit. They spot a signpost, which informs them of a local legend that says that the Crystal Pool can allow one to see those who have died. However, the person they’ve come to meet, Briar, is nowhere in sight, so Friede sets out to look for her while telling the children to wait. The trio’s first partner Pokémon start playing at the shore of the pond, but their playtime is interrupted when an agitated Milotic suddenly emerges from the water before them and promptly Terastallizes into a Ghost type. Left with no other choice, the children start to battle Milotic, but its movements and counterattacks prove too fast for them. Liko tries to use Floragato’s vine to hold it in place, but instead, Milotic ends up pulling Floragato underwater, forcing her to let go. Deciding on using a lure instead, Roy and Dot get an idea from a carnival game that Dot played back during the Countryside Harvest Festival. Floragato ties her vine around Quaxwell, who dances in the shallow water to lure Milotic in, at which point Floragato pulls Quaxwell to safety and Crocalor uses Disarming Voice. Surprisingly, Milotic uses Disarming Voice right back, and soon both it and Crocalor start singing to each other, with Milotic’s Terastallized state becoming undone in the process as the two song-loving Pokémon communicate through their singing.
