Plot
The President demands the search of the notorious Dr. Eggman who is hiding underwater inside the damaged Egg Fort. Down there, Eggman is seen holding onto Decoe and Bocoe, trying not to make a single sound. Back at the Thorndyke mansion, Chuck hands out passports and other documents to Sonic and his friends (much to the dismay of the latter). Meanwhile, Sonic and company flew over to the Southern Sapphire Sea for a well-deserved vacation. While riding to the sea by the X-Tornado, Tails finds out that another Chaos Emerald is near them, but it's in underwater. When they landed, they had to flee from an over-excited crowd of people to another location again.

After losing the crowd, while Amy and Cream have a swim, Chris discovers some solutions to help Sonic breathing while underwater but those plans failed. They buy underwater items and the owner tells them a legend that a ship sank along with treasure a long time ago. Sonic, Tails, Amy, Cream and Chris dived underwater and discovered the ship. They found the treasure as well as the Dark Blue Chaos Emerald. The Egg Fort arrives and Eggman sends his robot Clurken to battle Sonic.

Clurken has the upper hand due to the drag of water limiting Sonic's running speed while in underwater. With the help of Sam Speed, Tails gives Sonic a power ring and Sonic defeats Clurken, but Egg Fort escapes.

Trivia

 * There is a small crab that keeps causing trouble for Sonic throughout the episode. That crab greatly resembles Crabmeat.
 * When the X Tornado was reacting to the Chaos Emerald, Tails refers to a similar reaction when he was flying over Diamond Stadium in the episode "Unfair Ball".
 * Amy and Cream wear their bathing suits and sandals for the second time in this episode.
 * In the Japanese version, when Chris holds up a sign at one scene the text reads "Good kids won't study this and try it at home." Sonic also holds up a sign which reads (translated as) "You mean I'm not a good kid?".
 * While holding the hose that keeps Sonic from drowing, Chris hums a part of "SONIC DRIVE", the Japanese opening theme of Sonic X.
 * In one scene, Sonic shows signs of both claustrophobia and achluophobia.
 * In the Japanese version of this episode's end credits, Amy's voice actress (Taeko Kawata) is mistakenly uncredited.
