did you know that sb3 files don't need to have all of the assets in them, if they've already been added to scratch's cdn? sb3 files are usually a .zip file with all of the assets, but renaming a project json file to end in .sb3 allows you to open it, saving some upload time. I had no idea scratch worked like this.
if it's not in the cdn already, scratch will replace the missing costume will this cool mystery sprite :>
