Book Series

Pyjamasques, formerly known as Les Pyjamasques, is a picture book series created by the French author Romuald Racioppo on March 29, 2007. The series began on March 29, 2007 with the release of Les Pyjamasques et le Grogarou, the books are published by Gallimard Jeunesse. The book series is inspired by DC Comics' Batman comic franchise, the cartoons and books in Romuald's childhood, and his desire for history, nature, dreams and the nighttime.


Les Pyjamasques are three superheroes who are not afraid.

When midnight rings, the three inseparable put on their pajamas and wander in the night, instead of being in their bed.

Thanks to their strange pajamas, they find themselves endowed with special powers: Yoyo bounces like a rubber ball, Gluglu runs on the walls without ever breaking his face, and Bibou, with her wings, flies into the sky!

Thanks to their tenacity and courage, they live extraordinary adventures without ever losing their good humor!


When midnight rings, Yoyo, Gluglu and Bibou put on their pajamas and wander in the night.

Superheroes, Les Pyjamasques are endowed with special gifts that they owe to their strange pajamas: Gluglu sticks, Bibou flies and Yoyo bounces like a ball.


Development on Les Pyjamasques picture book series are dated back when Romuald Racioppo drew an early image of three prototypes of Yoyo which were intended to be the original characters of Les Pyjamasques as he claimed in his Facebook account to be the very first Pyjamasques drawing. He also came up with the creative idea for the series by getting inspiration from his childhood experience on what happens during in the night, how he felt like a hero and the similar events he would experience.

Eventually, as development progressed on the creation of Les Pyjamasques picture book series, Romuald Racioppo then created Bibou and Gluglu, and a refined version of Yoyo which would replace the prototype versions of Yoyo. And the first Pyjamasques stories debuted in 2007, together with the first merchandising.

With the popularity of Les Pyjamasques came the expansion of merchandising of the series to book fairs in which Romuald Racioppo would sign the person's name at a page with a drawn illustration of a Pyjamasques character. Then games, models and toys of the characters were created when Les Pyjamasques got itself a television series, as well as the books of Les Pyjamasques that would be expanded to focus on the television universe.

Since 2017, Romuald Racioppo would start expanding the picture book series to have a series of coloring pages, a giant coloring wall, mini-libraries and books containing more than one existing story.

PJ Masks

PJ Masks is a British-French-Canadian animated television series that was first broadcast in September 18, 2015. It follows on the adventures of the descendant counterparts of Les Pyjamasques; Catboy, Owlette and Gekko, who save the day by fighting against villains. The plots and settings very loosely followed the timeline of the actual picture book series, and it had a dark and mysterious atmosphere with a science fiction theme instead of having a light atmosphere with a mythology/folklore-based setting.


The Taïtikis is a spiritual successor to the book series that was created by Romuald on June 3, 2021.

TV Series Connections

While the books are published as a continuous series, there is a notable difference between the first 18 books, and the books from 19 onwards.

These differences include:

  • Certain characters getting more visual connections to their designs and the addition of new characters that directly reference the PJ Masks TV series (e.g. Bibou being given a visible feminine expression, Les Pyjamasques having costumes similar to the book counterparts, etc.).
  • The storyline gets a "soft reboot," and is changed to be more reminiscent to Miraculous: Tales of Ladybug & Cat Noir.
  • A slight shift in atmosphere.
  • The original art style of the picture book series has shifted slightly to be combined with TV series art style.


  • In 2011, Romuald Racioppo would state in a message that corresponds well to the mood of Les Pyjamasques is that he'd sold an original illustration of Les Pyjamasques for a Chanee-led association known as KALAWEIT who is protecting a Indonesian primary forest and the animal species that live there. Romuald Racioppo would also have the opportunity to spend a month in Indonesia with Chanee.
  • Some of the books shown that Romuald's illustrations of the characters are illustrated separately.
  • An English version of the logo is available in some concept art images of the PJ Masks television series. However, this is never used in any of the available books of the original book series.
