However, Nobita becomes sick and can't make it one night. Doraemon tries to feed Piisuke instead but comes home saying Piisuke is gone. It turns out though that because Nobita didn't show up Piisuke came looking for him. At first Nobita is angry that Piisuke came into town but doesn't stay angry long. Doraemon takes Piisuke back to the lake once the plesiosaur sees Nobita is ok. However, the next day when Nobita goes to visit him he hears that Piisuke was seen and when he gets to the lake it's flooded with reporters. Nobita is unable to get to Piisuke without being seen and goes home. When night comes, Nobita goes back to the lake to try to get Piisuke away from the reporters. Doraemon acts as a distraction while Nobita uses the shrink and enlarge torch to shrink Piisuke so that he'd get in a cooler box. He escapes with Piisuke and he and Doraemon use the time machine to take Piisuke back to the Late Cretaceous. On the way there however the time machine is attacked by hunters from the future who intend to capture Piisuke. Nobita, Doraemon and Piisuke manage to escape but the time machine is damaged. They leave Piisuke in prehistoric times and return home with Nobita crying the entire way. Gian and Suneo show up at Nobita's home and he's forced to eat a giant plate of spaghetti through his nose as he failed to show them a dinosaur. He tries to convince them that he does have a dinosaur but they don't believe him. When he goes to Shizuka's house to complain she doesn't believe him either. Angry, Nobita uses one of Doraemon's gadgets to show his friends Piisuke back in prehistoric times. However, they see Piisuke being bullied by sharp-toothed "Elasmosaurus". Doraemon says because they were attacked while on the time machine they've accidentally left Piisuke in Cretaceous America instead of Japan. Nobita immediately drags every-one back to the time machine against Doraemon's advice and they return to Cretaceous America to save Piisuke. They find Piisuke and Nobita introduces him to his friends, which also results in them apologising for their previous behaviour towards Nobita. They plan to take Piisuke back to modern times and then to Cretaceous Japan.
