Jerks and the Beanstalk.The Royal Knights take Katsuharu, his friends and Tommy to a village called Beanstalk Village that has a giant beanstalk in the middle. Dynasmon demands the location of a key, but the kids don't know what he's talking about so he locks them up with the villagers, the Mamemon. The Mamemon Elder explains that Katsuharu and his friends had previously visited and the Mamemon shared their food with them despite not having much. As a gesture of their friendship, the kids planted the Mamemon's last bean for them and it grew into the giant beanstalk. The beanstalk prevents the Royal Knights from scanning the land and they need the key to getting rid of the beanstalk to get the data. They kidnapped the kids because they believe they know where it is. Meanwhile, Takuya and the others are warned not to go to Beanstalk Village by scared Trailmon, but they hitch a ride on Worm when he tries to take off without them. They find the tracks broken and start using tracks from behind Worm to fix them with Takuya's determination to save the Digital World renewing Worm's spirit. At the village, Tommy and the others get free but are attacked by the Royal Knights who kidnap the Elder and tie up Tommy. Crusadermon tries to scan Katsuharu's Fractal Code, but he is saved when the others arrive. Takuya and Koji quickly evolve to EmperorGreymon and MagnaGarurumon, but their attacks have no effect on the Royal Knights and Koichi is taken hostage. The Mamemon attack, allowing MagnaGarurumon to rescue Koichi, but Dynasmon and Crusadermon beat up EmperorGreymon and MagnaGarurumon. Before they can be killed, the Mamemon Elder reveals that the key is a golden bean pod at the top of the beanstalk. The Knights destroy it and with it gone, they are able to scan the entire area while the Mamemon, kids, Bokomon, Neemon and Patamon escape on Worm. Katsuharu offers to take the Mamemon back to the human world, but they refuse to go and reveal they have another bean to plant to create a new beanstalk. Katsuharu and his friends return home on Worm, but not before Katsuharu has Tommy shove him onto the Trailmon so they are even from when he shoved Tommy on to enter the Digital World.
