Chris, Tails, Amy, Cream und Cheese gehen an den Strand, aber Sonic bleibt zurück, um ein wenig allein umherzulaufen. Während Amy am Strand liegt, träumt sie von ihrem Helden Sonic und beschließt, ein Halsband für ihn zu kreieren. Unterdessen hegt der finstere Eggman einen gemeinen Plan, um den Strand zu zerstören ...
Since Chris is going to attend the opening ceremony of a resort establishment, everyone goes to the villa of Chris' house. However, Sonic decides to run off somewhere else. Amy gazes at the sea, wishing to have come here with Sonic. Then, Dr. Eggman arrives at the ceremony's site and wreaks havoc with his robots intent on building his own amusement park in its place. Sonic, aided by Amy, arrives to save the day and Eggman is defeated by Amy, but ends up falling into the ocean, with Sonic going in to save her despite his aquaphobia.
Chris e i suoi amici vanno in un resort al mare. Il divertimento è interrotto dal dottor Eggman che rovina la festa, liberando i suoi robot per costruire un parco marino.
Amy, Tails, Cream y Cheese van la playa Costa Esmeralda y Chris va a la inauguración de un nuevo y lujoso hotel cerca de allí en representación de su padre. Pero la inauguración es arruinada por Eggman, quien quiere construir un parque de diversiones. Ante esto, tails y sus amigos van al rescate de Chris y más tarde Sonic, quien no fue a la playa debido a su miedo al agua.
Chris's forældre får en invitation til at deltage i åbningen af en ny familieattraktion ved søen. Chris tager afsted istedet for forældrene. Amy er glad, men får ikke lov til at gå med hen hvor der er så mange mennesker. Alligevel tager Amy med til Torndike familiens private strand. Sonic er som altid taget på eventyr.
