In Japan, Grandmaster Glitch is at a railway station, wondering where his grimbots have gone. Some excited bleeps further down the platform reveal that they've jumped into the driver's cabin of a bullet train and are happily pressing all the buttons! Glitch shouts at them to stop but it's too late: he quickly jumps onboard as the doors slam shut and the train moves off - leaving the station without it's driver. Meanwhile, at the next station, the Go Jetters are excitedly waiting with their tickets to ride the bullet train.The train approaches but doesn't stop, racing past the Go Jetters as Grandmaster Glitch shouts out of the window. The Go Jetters realise the train has been glitched!

When Grandmaster Glitch discovers his Halloween pumpkin isn't as big as the Grimbots' one, he goes in search of some fertilizer to help it grow. Meanwhile, Xuli is testing her new sonar-equipped G.O. Dive at the Gua Rusa cave in Borneo. Gua Rusa is so big, a jumbo jet could fly through it. It's home to millions of bats, and Glitch is after all the bat droppings to use as pumpkin fertiliser!
