World 9-1 (Super Mario Maker for Nintendo 3DS)
From the Super Mario Wiki, the Mario encyclopedia
World 9-1 is the first level of World 9 of Super Mario Challenge from Super Mario Maker for Nintendo 3DS. It is the same as World 1-Airship in Super Mario Bros. 3, but more closely resembles 1-Airship Remix from Super Mario Maker. One main difference between this and the Wii U version is that Bullet Bills are shot out of the Bill Blasters.
