The Valle Grande Games skateboarding competition is coming up, and the winner gets a brand-new board. That means, if Coco wins, Catalina might finally get a skateboard of her own—Coco’s old one. The trouble is, normally fearless Coco has lost her skateboarding mojo at the worst possible time. Cat discovers that Coco has outgrown her lucky flannel, and without it, she’s lost her confidence. This could be Catalina’s big chance. She can enter the competition herself. If she wears the lucky flannel—and uses the magic sewing kit to make some special alterations—the judges might see a skating star and award her the new board. Which sister will come out on top?
