At the moment, we have a script that shows the next background when the user clicks on the Next arrow. Let's create a sound effect to signal the next slide:
Select the Next sprite and add a play sound () block from the Sound palette to the script that starts with when this sprite clicked.

Click on the Scripts tab.
