Hello! To get the sprite, go into the Costumes tab inside the project, right-click the small sprite, and click "Export". Hope you like it! By the way, the reason it's so small is so that you can export it at a size that's okay for a profile picture.
I used Pixel Studio and @TricolorGlobe62 's profile picture/OC as reference. Original owner: @TricolorGlobe62
