Nobita's Black Hole

Nobita always leaves leftovers, which makes Nobita's mother unhappy. Doraemon feeds Nobita a "Mini Black Hole", and Nobita eats 6 bowls of rice in one go, and shows off to Gian and others, but Gian is not convinced. Nobita eats the black hole while Doraemon is asleep, and uses the "Duplicate Mirror" to copy 100 Dorayaki, and competes with Gian in eating. As a result, Gian can't eat anymore after eating 26, and Nobita eats all the remaining dorayaki and wins. Nobita wins, but he is still hungry, and Shizuka goes home to get snacks for Nobita. Nobita falls asleep after returning home, and the black hole is out of control, swallowing everything in the room, and almost swallowing Shizuka. Fortunately, Doraemon arrives in time and tell Nobita to shut up and drink the "Black Hole Decomposer", but Doraemon is sucked into Nobita's mouth by Nobita's black hole. Shizuka gives Nobita the "Black Hole Decomposer" given by Doraemon, and then the black hole is expelled. Finally, Doraemon is also expelled by Nobita in the toilet. But after the black hole disappears without a trace, everything in Nobita's room is messed up in the toilet, and Nobita's mother quickly criticizes Nobita.
