1x103 - Doraemon

Gian, Suneo and Shizuka are riding bikes but Nobita does not join them because he cannot rise a bike. Doraemon gives him a wonder rope (one of many he has), a harness which enables a cat or dog to be like riding a horse. Nobita falls off a cat, then a dog and as he saddles the second dog, along comes Gian and Suneo riding a cat and a dog. Shizuka gets on the dog Nobita just saddled and they ride off, leaving him alone again.
