Laura, Kana, Travis, Roberto, Yume-chan, Zack and many other kids from the school are on a summer trip hosted by Goldie and Curtis. The Ham-Hams also hitch along with them. Laura and Roberto both forget their swimsuits and so they both decide to help out at the cafe. To try and get his 'title' back, Boss looks for a sea shell that resembles Seamore's and tries to swim using it. This doesn't work and he falls down a cliff. Seamore jumps in to rescue him. The tide then changes and they both drift out to sea. Panda brings along an inflatable boat and they use it to rescue them.
