On the next visit, Nobita brings his friends with him, and they play in a meadow. Lopplc takes Nobita to his friend Morina who continuously ignores them. After they enter the spaceship, they see Koya Koya Planet, and meet Lopplc (12 years old). She shows them the passageway through Nobita's floor into the spaceship. Nobita wakes up, and Doraemon hears somebody steal food from the fridge. A little rabbit from the alternate universe named Chammy opens the door between the dimensions using a hammer. While Nobita is sleeping, he suddenly feels the floor is trembling, like an earthquake. Two alternate universe creatures, Lopplc and Chammy, are escaping from an enemy ship. But finally caught by him and beaten off well. Gian gets angry upon him, and he runs toward Shizuka's house to save himself. But they chase him and drop him down a manhole. Meanwhile, Nobita's friends get him to retrieve a ball from a group of tough baseball players. The Professor (who was Morina's father) wanted to fix the spaceship, but another lightning strike took him to another dimension. A sudden bolt of lightning damaged the ship, causing a power failure. Everyone had to escape using a giant ship. The quake was so massive that the planet was destroyed. Suddenly they felt an earthquake on the Koya Koya Planet. Seven years ago, Lopplc and Morina were playing at a park. This section may need to be rewritten to comply with Wikipedia's quality standards.
