Perfect for kids, classrooms, parties and your own Treehouse Comix.

About Captain Underpants names

The Captain Underpants name generator is really Professor Pippy P. Poopypants' Name Change-O-Chart 2000 from Dav Pilkey's fourth book, in which the professor forces every person on Earth to take a ridiculous name. The chart works in three steps: the first letter of your first name gives you a silly first name (Stinky, Lumpy, Buttercup, Gidget, Crusty), the last letter of your first name gives you the first half of a surname (Diaper, Toilet, Giggle, Bubble, Girdle), and the last letter of your last name gives you the ending (head, mouth, face, nose, tush). Put them together and you get the kind of name George and Harold would scribble onto a Treehouse Comix cover: Poopsie Monkeyshorts or Fluffy Lizardtush.

This generator follows the same recipe without being a lookup table, so every spin gives a new combination: a goofy first name (food, sound effect or squishy adjective) plus a compound surname built from something gross and a body part. Alongside those you will find the real cast, from Mr. Krupp and Melvin Sneedly to Wedgie Woman, Dr. Diaper and the Turbo Toilet 2000, and original heroes and villains in the same spirit: Captain Thunderbuns, Sir Toots-A-Lot, the Bionic Booger Beast.

Use it for read-aloud giggles, classroom comic projects, birthday party name tags or naming the villain in your own flip-o-rama.

How to choose Captain Underpants names

  • Want your official Name Change-O-Chart result? Use the first letter of your first name, the last letter of your first name and the last letter of your last name with the book's three columns, then compare it with a random spin here.
  • For a homemade comic, give the hero a title plus underwear word (Captain, Commander, Sir) and the villain a Professor or Doctor name followed by something that belongs in a bathroom.
  • The funniest names balance one food or animal word with one body part; stacking three gross words in a row stops being funny and becomes hard to read aloud.
  • Keep it kid-safe: Pilkey's humor is toilets, wedgies and boogers, never anything cruel, so names should make a seven-year-old laugh without making a teacher frown.
  • Assign names to a whole class or party at once, then have everyone draw their character; the combination of name and drawing is where the Treehouse Comix magic happens.

Frequently asked questions

Which Captain Underpants book has the name change chart?

Professor Poopypants' Name Change-O-Chart 2000 appears in Captain Underpants and the Perilous Plot of Professor Poopypants, the fourth book in Dav Pilkey's series, where Tippy Tinkletrousers tries to force everyone on Earth to adopt names as silly as his own.

Are the book's real character names included?

Yes. You can land on George Beard, Harold Hutchins, Mr. Krupp, Melvin Sneedly, Ms. Ribble, Professor Poopypants, Wedgie Woman, Dr. Diaper, the Turbo Toilet 2000, Sulu the hamster, Super Diaper Baby and characters from The Epic Tales of Captain Underpants series, mixed with hundreds of original silly names.

Are these names appropriate for young kids?

They are written to match the books' humor: underwear, toilets, boogers, burps and wedgies, with nothing mean-spirited or rude beyond that. Parents and teachers can use them in classrooms, on name tags and in homemade comics.

Can I use a name for my own comic or school project?

The original names here are free to use for fan comics, class projects and parties. Character names from the books belong to Dav Pilkey and Scholastic, so keep those for fan fun rather than anything you plan to sell.
