Synopsis
Fandom WikiIn school homework, Nobita decided to observe wild birds with Shizuka, Gian, and Suneo and they will all meet at the Open Lot. So Nobita asked Doraemon to take him to the mountain, thinking to observe the unusual bird.
However, Doraemon said that he have to go out and find the lost cat. Nobita cried for Doraemon for not not going to the mountain. So Doraemon puts out the "Mini Doraemon" that looks exactly like Doraemon from his pocket and Doraemon leaves Nobita. Despite it is in small size, Mini Doraemon seems to have secret tools in his pocket.
Mini Doraemon takes out the "Take-copter". However, Take-copter is too small to support Nobita's weight and he falls to the ground. After that, Nobita came. With Mini Doraemon they decided now to go to the mountain. So Mini Doraemon puts out the "Anywhere Door" but the door is too small to enter. So they decided to use the "Small Light" to become smaller. But they become too smaller than Mini Dora so they got blowed by the wind in the Anywhere Door that is heading to the mountain except Mini Dora because he didn't use the Small Light to himself.
At the mountain, They used again the Small Light to return to their original forms and they see the beautiful appearance of the mountain. While they are at the mountain, All of them become hungry so Mini Doraemon puts out the "Partial Gourmet Table" that is too small and the foods appeared at the top of the cloth are small too. Suneo suggested that they use Anywhere Door to ask some snacks from his mother but only scared who spewed tea at him. Everyone saw a cat on the tree, and everyone planned to save it. Gian projected Mini Dora onto a tree, let an eagle eat Momotaro Jirushi's Millet Dumplings, carried Mini Dora and the cat back to the ground, and Doraemon came to everyone afterward.
