Just click the flag. If it's slow, it's not lagging. I just made different slides and programmed it to go to the next backdrop every few seconds. Don't judge, I'm not good at animating or drawing on my laptop. Also, I know it's a normal Sunflower and not the real Plant Hero. I can't draw her, so I just made another guy.
Credit to PvZ for the existence of Sunflowers. I love you all Sunflowers ;) Oh, and @catboi321 for making funny animations. You must see them!
