Hint-Finding Trampoline

Synopsis

Doraemon dejectedly reads a missing manga volume from a set Dad brought home. The final volume is nowhere to be found. For a desperate search, he produces the "Trampoline"—jump high while naming the missing item, and the device reveals hints through flashing lights. Coating the trampoline in the vacant lot, Doraemon names the missing manga volume and bounces. A distant flash guides them to a bakery, where they find the volume in an old book collection. Overjoyed, Doraemon accepts the gift. Moments later, Sneaky appears with his own problem: a missing baseball card number—what will the device locate for him?
