Super Diaper Baby Books in Order

The Super Diaper Baby books are a spin-off that lean hard into the “kid-made comic” energy that runs through Captain Underpants. In the story world, Super Diaper Baby is the superhero comic George and Harold create, so the tone is intentionally messy, loud, and full of the kind of jokes kids scribble in notebooks when they’re supposed to be paying attention. The books embrace that homemade feel, with playful fonts, exaggerated sound effects, and lots of doodle-style art that looks intentionally homemade.

Super Diaper Baby is, as advertised, a diapered superhero baby. He’s tiny, unstoppable, and always running headfirst into danger, usually with a big grin. The plots are built like comic-book spoofs, with exaggerated villains, ridiculous gadgets, and action scenes that are meant to be read fast and laughed at, not analyzed. Problems get bigger, stranger, and grosser, and the solutions are usually whatever would make two kids giggle the most.

It reads like something kids would draw in the margins.

The series also keeps the pages feeling interactive. You’ll see comic panels, goofy captions, and visual jokes hiding in the corners. The layout moves quickly, so a reader can fly through a chapter, feel successful, and still get a full story. That’s a big part of why these books work for reluctant readers and kids who prefer comics, the art never feels “extra”, it’s the main language.

Even though the humor is over-the-top, the worldview is friendly. The hero is a baby, so the tone stays kid-safe, and the books are more silly than scary. If your household likes toilet jokes, superhero parodies, and absurd villains with dramatic names, this is a good match.

If you’re already in the Captain Underpants zone, these books are a fun detour that still feels familiar. They share the same prankster voice and the same affection for creative kids who would rather make comics than do worksheets. You don’t need a lot of series knowledge to follow along, because the point is the momentum and the jokes, not continuity.

There are only a couple of main entries, so the reading order is simple. Start with The Adventures of Super Diaper Baby, then move to The Invasion of the Potty Snatchers for a bigger, weirder sequel. If you like the idea of a superhero comic that feels like it was made by kids, for kids, this series delivers exactly that.
