Happy Trails Pt. 2: Jumping The Shark.After the events of the previous episode, the survivors are stranded on a deserted island. The bus is in shambles, the ocean is shark-infested, and many have died in the accident. Flippy creates small graves for those who died in the crash, while the others look on mournfully. The next day, Giggles happily catches a fish in the ocean for food, using a long pointed stick as a makeshift spear. a Jellyfish swims by and zaps her left foot, causing her to shriek in pain and curiously observe the bump on her foot. Later that day; during night, Giggles is suffering from extreme chills, wrapped in a blanket, and her stung foot is incredibly swollen. The scene cuts to Flippy sadly pounding down another grave with Giggles' bow tied around it, indicating that she died of hypothermia. When Flippy is done pounding in Giggles' grave, Lifty and Shifty reveal they have an inflatable raft the group can escape on. As the group sails away from the island as Lifty and Shifty paddle with their hands, everyone is relieved and in good spirits. Unfortunately, as Flaky sits down, her quills pop the raft, causing the raft to start sinking as a shark swims along. The group hurriedly swims back to the island, but Lifty and Shifty are taken and eaten by the shark. As everybody catches their breath, Flaky looks on nervously at her fellow members, who are obviously furious at her for popping their only ride home. As the scene changes to night, Flippy Angry evilly as he pounds Flaky's grave into the sand, while the others watch on the background with evil expressions, implying that at least one of them killed Flaky. The next day, the school bus and the tree on the island are gone and in their place stands a rocket ship made up of the bus parts. The group boards their creation with makeshift helmets made of coconuts, and they lift-off, singing the theme song as they go. Eventually, the rocket stops moving upwards. They throw several weighty objects out of the rocket, one of which being Lumpy, and the rocket continues upwards. Sadly, now the rocket moves too fast and it is headed towards the sun. Sniffles' head explodes as they get closer to the sun, while Handy and Flippy are suffering from second and/or third-degree burns. Back on Earth, Lumpy makes the best of his situation by relaxing in a chair and holding his sock over a fire. A "puff!" suddenly appears in the sun, indicating that the rocket ship made contact with the sun, without Lumpy even noticing. As the episode ends, Lumpy begins applying sunscreen to his arm.
