Otto tries to swim for help, but gets swept away by the current and picked up by Chinese fishermen. Otto is excited, thinking they will help him rescue the kids, but they actually plan to use him for slave labor below deck of their ship. The students swim to a nearby tropical island, where Bart tries to tell everyone that being stranded is fun and imagines a lavish lifestyle there. Reality sets in when the island is found to be largely barren and the kids lack survival skills. With no food or adult supervision, the kids rely on snack food retrieved from the sunken bus by Bart, while Lisa sets up a ration system. They awake the next morning to find the snacks all gone. Suspecting Milhouse, he blames the loss on a mysterious island ""monster"", which does not hold water with most of the kids. As they prepare to lynch him, Lisa reminds them of why they traveled in the first place - the Model UN - and Milhouse is allowed a trial, with Bart as a judge.
