Dennis and Gnasher

Humiliated by Walter during a hectic game of hide and seek (which soon cumulates into a national frenzy when adults begin to get tagged), Dennis decides to compete against him in a Blue Peter painting competition, with a 'little help' from a certain four-legged friend.

Dad is incredibly determined that the Menace family holiday will be incident-free, but Dennis' usual mayhem, an animal-hating guest-house owner, and a suspected burglary back home do very little effort to liven up his spirits…

When Dennis beats Walter in a racing car competition, The Colonel is determined to find what made his engine-free vehicle tick.

The discovery of a large stone-age mural in the Menaces' front garden causes Dennis to daydream on what it would be like to live in prehistoric times… and to somehow witness the creation of the wheel.

Dennis's plans to create chaos at the school parents' evening are seemingly thwarted when his parents arrange The Colonel to baby-sit for them.

Dad's ghastly aunts return from their 20-year long holiday expedition 10 years earlier than expected, and quickly prove themselves to be a big match for Dennis.

The Menace family are swindled by ruthless tycoon Clint Katzenberger, who tries to root out an oil field beneath their house.

A new Mega Mall suddenly opens in Beanotown, but Dennis and Gnasher quickly realise something's not right...

Gnasher finds himself hunted down by sinister rat catchers when the Colonel's 'adventurer' cousin Hugo claims he is really a dangerous 'super-rat'.

Dennis's search for the existence of the Tooth Fairy takes him (along with Gnasher and Pie-Face) into the farthest reaches of his mattress, where he ends up in a war zone between the Fairy Freedom Fighters and a bunch of goblins.

Mum's new job at the art gallery is threatened when a group of scurvy dogs steal the gallery's main attraction as a new figurehead for their ship. It's up to Dennis and his crew to battle the pirates and return the stolen statue.

Dennis competes in a race against Walter to become school prefect, and is determined to make it to the building early for once…

The series finale. Expecting a 'Model Space Racer Jet Set Kit', Dennis and Gnasher instead receive Jacques, a hulking, information-guzzling fellow who becomes a huge hit with the school and wins the heart of Matilda.
