S1·E1208 Let's Skate on the Moon Craters!

Nobita is mocked by Gian and Suneo at the park for not being able to skateboard, though Suneo gives him an old board to try. Feeling frustrated, Nobita asks Doraemon for help, and Doraemon brings a gadget called the “Otasuke Hat,” which is meant to prevent injuries when falling from sliding sports. However, Nobita is too scared of falling and cannot use it properly. Later, Shizuka arrives and skillfully rides a skateboard while wearing the hat, impressing everyone. Doraemon becomes disappointed in Nobita’s fear, though he reflects that Nobita might feel more confident in a lighter-gravity environment.
