If you loved how Princess Smartypants set ridiculous trials for her suitors and then turned Prince Swashbuckle into a toad rather than say "I do," you'll cackle at Princess Sue in The Worst Princess. She dumps her pompous prince, teams up with a dragon, and blasts off into her own adventures—all in jaunty rhyme and with wickedly funny art that channels the same irreverent spirit.

Like the moment Smartypants refuses marriage on anyone else's terms—and zaps a pushy prince—Elizabeth in The Paper Bag Princess outwits a dragon to rescue Ronald, only to realize he's not worth keeping. Her final "bum" put‑down has the same triumphant, laugh‑out‑loud autonomy you enjoyed when Smartypants kept her castle just the way she wanted it.

If Smartypants's monster menagerie and transformation spell made you grin, you'll enjoy the sparkly gadgetry and fairy‑tech in Interstellar Cinderella. Instead of chasing a prince, Cinderella fixes rockets, zooms to the space ball with a robo‑mouse, and chooses an apprenticeship over a proposal—mirroring Smartypants's magical flair and firm "my life, my choice" vibe.

As with Smartypants refusing to parade suitors and preferring her own unruly pets, Princess Isabella in Princess Pigsty rejects tiaras and lessons to work in the pigsty, learns real‑world skills, and stands up to royal expectations. Her stubborn, funny independence scratches the same itch as watching Smartypants keep her freedom—no wedding bells required.

If the upbeat ending of Smartypants—where she gets exactly the life she wants—made you smile, Zog will, too. Princess Pearl befriends a training‑hard dragon, decides she'd rather be a doctor than a damsel, and teams up with Zog to help creatures in need. It's the same sunny, rule‑flipping spirit you liked when Smartypants rewrote the fairy‑tale script.
