Grandmaster Glitch has been invited to Djenne in Mali, Africa, to visit the people and to see one of his favourite things at work - mud! He is especially impressed by the spectacular Great Mosque of Djenne, the largest structure made from mud in the world. But mud brings problems, and during the rainy season the rain causes damage to the walls of the mosque and the mud houses, so the local people get together to help repair them. Glitch wants to help, but when he realises they have to do this job every single year, he makes a massive umbrella to try to keep the mosque dry so that the local people don't have to repair it again. Although Glitch was only trying to help, things start to go wrong. The huge Grimbrella swings too close to the mosque and goes out of control. The Go Jetters need to fix that Glitch!

While in Mexico, Glitch takes a short cut through the Cave of Crystals, a hidden space that contains some of the biggest crystals in the world! On his way through the cave the clumsy Grandmaster falls off one of the crystals and into a deep ravine. It's very hot in the cave and Glitch and the Grimbots are in trouble. Back at the Go Jet Academy, the Go Jetters receive a video message from Glitch asking for help. Fortunately, they have just been testing out their brand new GO Suits that allow them to control their temperature.
