S02E03 — The Robot Club's Dream, Pinocchimon's Temptation

The members of the school's robotics club are frustrated because they keep failing to build a robot good enough to take part in the upcoming competition when they approached by Xros Heart's old friend, Puppetmon, who offers them a chance to take part in a greater project. The next day, while told to deliver a notice to the absent Tokio, Tagiru learns from Taiki that all other members of the robotics club are also absent from school, and fearing it to be Digimon related, he and Yū accompany him to Tokio's house, just to find him working on some machinery. Figuring that Tokio is deceiving his mother in thinking he is going to school to stay home, Xros Heart witnesses Tokio entering into the DigiQuartz through his computer. By following him there, they learn that Tokio and the other missing children have been building a GigaBreakdramon under Puppetmon's orders. Taiki and Shoutmon confront Puppetmon who seems to not remember them at all and launches GigaBreakdramon against them.
