I actually had a lot of difficulty with this in the beginning -- I'm a bit rusty with creating Scratch projects! When I first used Scratch, I remember being so frustrated at how a simple task could be extremely difficult or roundabout to implement in Scratch. I checked out a few projects in the studio which helped me debug some of my errors (like forgetting I needed a forever to clone the soccer balls). This was fun, not my best work, but fun!
