Just press the green flag
@CallMeAlt made this for me, if you want to know how she got the licking cat this is how: open a new tab, search "licky cat", press on one of the cats that you like, right click on the picture and then press "save image as" and then save it! when you get in scratch press create, ok now hover your mouse above where you choose a sprite. Now press upload. Then upload the picture. Go to costumes. Then you'll see the movements. For coding, press "see inside" next to the name of this project.
