The Lost-Item Delivery Machine

While at school, Nobita accidentally loses his homework. Doraemon uses the "Delivery Machine" to retrieve it and also has Nobita take his umbrella to his father, who is at work. However, while Nobita is performing magic tricks for Suneo and the others, Doraemon uses the gadget to help Nobita conjure a baseball and a vase. The greedy Nobita then tells Doraemon he wants to conjure a pigeon and a lion. In the end, he accidentally conjures Doraemon instead, which angers Doraemon, who scolds Nobita. Surprised, Suneo and the others think Nobita's magic tricks are quite impressive.
