The Go Jetters have been invited by the Korowai tribe to visit their village in the rainforest of Papua in Indonesia. They are an ancient tribe who build their homes above the ground, safe from floods and insects, using everything around them in the forest. Meanwhile, Grandmaster Glitch is also in the rainforest, trying to build the tallest treehouse in the world. When he sees that the Korowai's treehouse is even taller than his, he tries to get his even higher. But Glitch has built his treehouse from metal, not from things found in the forest, and his treehouse is not safe...

Greedy Grandmaster Glitch has been gorging on chocolate and wants more! The Grimbots discover a place called the Chocolate Hills on Bohol Island in the Philippines and take him there. The Chocolate Hills were created over thousands of years by water and wind eroding the rock, making a hilly landscape. Grass and ferns grow all over the hills and during the dry season they turn a chocolatey brown colour, making it look like the hills are covered in chocolate! The Go Jetters are also heading to the Chocolate Hills, but when they get there they are shocked to discover that the hills are covered in real chocolate. Glitch has turned the Chocolate Hills into a chocolate theme park!
