The trio stops off on the planet Odwarla, an ocean planet inhabited by merfolk for lunch. When Hatchi is reluctant to use his Smartbracelet, he and Ikku end up having to work off the cost of their meal, while Robby gets food poisoning.

Robby and Hatchi visit Hamama II, home of the Great Eel Festival. Little do they know that Yang and his gang have tracked them there, where they are also enjoying the festivities, as Yang is affected by the eels' legendary powers of virility.
