After beating Chuck and earning the Storm Badge, Ash and co set sail for the Whirl Islands. But along the way they're pulled in by some fierce whirlpools caused by a submerged Pokémon. After being saved they meet again with Professor Elm, who informs them of the upcoming Whirl Cup event which Ash and Misty decide to compete in. Will this bring Misty one step closer to her goal of being a Water Pokémon Master?
This episode is part 1 of the Whirl Island 13 part arc.
Misty stated she wanted a Corsola of her own. She will catch one in JE098: A Corsola Caper.
This was the season premiere of Pokémon: Master Quest.
As such, the season gets a new theme song.
The English place names on the Whirl Island map move between shots, presumably due to them being superimposed over the original Japanese text.
