The Stupidity Time Bombs

Dekisugi recently visits Tokyo Disneyland and discusses his experience with Shizuka. They mention the 3D movie on the big screen, but Nobita says ice cream is more fun. On the way home, Nobita feels ignored by Dekisugi and Shizuka, feeling like a fool. When he gets home, his mother is about to scold him, so Doraemon takes out a "Timed Stupidity Bomb" and throws it at her, making her start clown around and stop scolding him. Seeing how funny the gadget is, Nobita wants to embarrass Dekisugi in front of Shizuka. On the way, he discovers Gian is going to sing a sad song for Suneo, so he makes Gian clown around, making Suneo laugh non-stop, which leads to his own tragic end. Nobita then finds Dekisugi and takes him to Shizuka's house, attaching the "Timed Stupidity Bomb" to his back. Unexpectedly, Dekisugi goes home to change clothes, and the bomb explodes in his mother's hands. On their next trip, Nobita attaches another bomb. Upon arriving at Shizuka's house, the three chat, with Nobita eagerly anticipating the bomb's detonation and Dekisugi's antics. However, Shizuka notices the bomb on Dekisugi's back and pulls it out. Doraemon and Nobita rush to grab the bomb, but in the end, they are the ones who pull the stunt, and Doraemon turns into a tanuki (raccoon dog).
