While their friends visit Kiawe’s farm, Lana and Ash decide to go fishing. At Olivia’s suggestion, they head to Brooklet Hill, where a Totem Pokémon is rumored to live!

After helping an injured Wishiwashi and catching a Feebas to prove herself to the master fisherman who guards the lake, Lana manages to hook the enormous Totem Pokémon, and the battle begins! The Pokémon is strong, but Lana hangs on with fierce determination—and in its own determination to help her, Popplio learns Aqua Jet! Defeated, the Totem Pokémon scatters into a school of Wishiwashi—and one of them presents Lana with a Water-type Z-Crystal to use with her new Z-Ring!
