Free rounded squares! -To use, go inside and ungroup the costume that has the one you want to use in it. Delete the rest, and you're ready to use it! The squares are quite easy to recolor if you don't like the current colors; they are only one shape. However, if you want a solid color, you must do a gradient fill with both colors being the same.
Around 50-60 rounded squares total, although most of them have gradients.
