While making a cake, Carrot and Mindy find they are one are short one ingredient, so they head to the store. But Carrot accidentally pushes a wrong button on the wagon's newly-updated control panel, and they take off into outer space! Using a diagram, methodical experimentation, and record keeping, Mindy and Carrot figure out how to properly fly the saucer back home, where they finally finish the cake. Mindy has a problem: now that she's been to space with the bigger kids, she realizes how much there is out there to see! How can she decide where to explore next? Sydney asks her mom, Dr. Skelley, who presents them with the very first edition of Commander Cressida comics! In reading the comic book, Mindy comes to appreciate that she, like Commander Cressida, can explore space "one adventure at a time."
