Story
When the Sablé Prince is swindled by Mandola (again), she claims she and Polnareff will be taking a vacation here. After finding out he has been duped, he makes his way to Hop Hop Springs in order to make her pay. On the way, he is attacked by a snake and, defenseless as a frog, succumbs to it.

He's awoken by a beautiful maiden, who later turns out to be Mandola playing another trick on him. He's enraged at first, until he realizes he's finally turned human again. He now has the ability to shift between human form, by fainting or eating a Joy Fruit, frog form, by touching cold water, and a new snake form, by eating the Hot Springs Eggs of Hop Hop Springs. He moves onto Spring Hill to ring the Spring Bell...

Trivia

 * One of the resident bathers says "Splish splash! I was taking a bath...", which is a reference to the Bobby Darin song, "Splish Splash". In the Japanese version, he says "ばばんば ばんばんばん ハー ビバノンノン！", a reference to the song "What a Nice Bath!" by the Drifters.
 * The Japanese name, Gerobeppu Onsen, is a reference to two popular Japanese onsen, the Gero Onsen and the Beppu Onsen. Gero Onsen was also likely chosen as a name due to the added frog pun, as "gero gero" is onomatopoeia for a frog croaking.
