Hey, instead of remixing this, press 'See Inside', and go to the Backdrop's Sounds. See that audio? Good. Look for your 'Backpack', which should be at the bottom of the screen. Now drag the audio down into the backpack, and go insert it into your scratch! Now, you may be wondering, 'How do I insert it?!' Well, you go to your scratch, go to the audio, drag the audio from your backpack to the audio list, and BAM! You have to use the sound block for the audio to play, if you didn't already know.
