That's right! The Super Ball power-up from Super Mario Land returns in Super Mario Maker 2! It behaves almost exactly as it did in the source game. It also plays remixed Super Mario Land music and sound effects (the sfx aren't adjusted whatsoever, they're just from the source game.) when you have the power-up.
This time, when I saw the official, it wasn't game-accurate. I had to make these sprite edits. These look more like the original game.
