Geronimo Stilton is an Italian children's chapter book series created by Elisabetta Dami[1] and written under the pen name of the title character.

Geronimo is a nervous, mild-mannered mouse who prefers a quiet life, yet keeps getting into faraway adventures with Thea, Trap, and Benjamin in both fictional and real locations.

Inspired by Patch Adams, who participates in Clown Care, she told humorous and adventurous stories starring the character of Geronimo Stilton and teaching morals to entertain patients.

I invented and told funny stories about a clumsy mouse that had lots of adventures, with twists in the plots and guaranteed happy endings.

Thanks to him I became a mum to millions of children and experienced the friendship that helps one achieve everything, as well as honesty and sincerity that instill value in every single gesture, not to mention the curiosity and sense of adventure that keep you going.

The series is set in a parallel universe based on space opera, featuring Geronimo Stiltonix as the captain of the entire spaceship MouseStar1.

The series is set in the Viking Age and stars Geronimo Stiltonord, who lives in the village of Mouseborg and faces fiery, mouse-eating dragons every day.

Publishers Weekly's review of Lost Treasure of the Emerald Eye praised the book for its fast pace, chapter format, full-color design, and usage of colored typefaces.

[11][12] Its review of Creepella Von Cacklefur entry Fright Night felt the plot wasn't "the strongest of Stilton spinoffs".

[13] Its review of The Kingdom of Fantasy entry The Enchanted Charms was mixed, criticizing the plot for not being original and appealing enough, but praising the art and incorporation of puzzles.

[20] Sony Computer Entertainment partnered with Virtual Toys to develop two video games based on The Kingdom of Fantasy series for PlayStation Portable.

The film is a co-production between Radar and Italian company Atlantyca Entertainment, which also produced the television series, with DreamWorks Animation veteran David Soren attached to write and direct and Anthony Tringali, Michael Napoliello and Maria Frisk set to produce under Radar Pictures.
