Comet, Sapphire, Shamrock, and Twilight travel to the royal baking competition in the capital city Sunshine Springs that Comet is a contestant in. Comet is eager to show off her baking skills and have fun with her friends! But when Comet meets the other bakers, she gets worried. Pete, Leopold, and Lavender dedicate all their time to baking and studying cookbooks, but Comet pursues other adventures like ghost hunting and exploring. Does that mean she's not a good enough baker? Is she really up to the challenge, or should she just go home before she lets her friends—and herself—down?
