Ten-year-old Dennis is a kid with an extraordinary imagination, awesome skills and a fearless attitude. Dennis is inseparable from Gnasher, a stray dog adopted by Dennis and now his best friend.

Dennis and Gnasher do first, and think later, which constantly gets them into trouble. They act on instinct, love the thrill of the chase, and push themselves to the limits.

Dennis' epic daring and Gnasher's comical indestructibility make for a fierce and funny friendship. Every kid either wants to be them, or be part of their gang.

In their latest TV adventures, they are joined by their irrepressible, adventurous friends: Rubi, JJ, Pieface and his pet potato, Paul.


Together they ramp up the energy, cook up crazy schemes, get into all sorts of scrapes and adventures and take on every challenge flung their way, no matter how big.


The boring grown-up world is their nemesis - with its tedious rules, power-hungry ways and sinister plans to shut down adventure.

Music is woven into the fabric of the show; it is part of the texture, the storytelling, almost a character in itself - a musical heart-beat!


Dennis and his friends form a band, which features in lots of our stories and their music forms the base of our series soundtrack. This tonally sets the musical vibe for the series as a whole.

Dennis & Gnasher: Unleashed! is an eclectic combination of classic Beano ingredients and fresh new characters and attitudes, teamed up with outstanding animation and production values to give these iconic everyday rebels the perfect showcase for their comedy, pranking and daring defiance of all things dull.
