Just press the green flag and enjoy the music! If you use this,please give credit! If you want to use this,you have to put the sprite 1 and the cat in your project. I might make a reamake of this at some point.The scratch music extension really isn't that great for music.The timing and the dynamics are messed up and weird and the project easily lags which results in the music sounding weird.If I were to do a remake I'd make it with an actual music program or record it.
