Sooty will celebrate 75 years in showbusiness in 2023, with the distinctive yellow bear's current guardian saying simplicity is the key to his enduring popularity.
Sooty will be joined by sidekicks Sweep, Soo and Richard Cadell for a theatre tour and new TV series next year.
Before that, there is a stint in pantomime alongside Jason Donovan and Faye Brookes in Southampton and a charity Christmas single, The Most Magical Time of the Year, with all proceeds going to Childline in the UK.
The slapstick comedy that still delights audiences of all ages has changed little since Sooty first found fame by whispering in the ear of his creator, Harry Corbett.
Cadell said keeping the traditional format has been key to Sooty's success: "I think it's just the simplicity."
He told the PA news agency: "Nobody's stupid. I think we all kind of probably have an idea how Sooty is working, but it doesn't matter.
"And I think the fact that we're all in on the joke means that it's been able to carry on. There's nothing complicated about it, and that's the key to its success."
Sooty started life as a plain yellow bear that magician and puppeteer Harry Corbett found in a shop in Blackpool, Lancashire in 1948. The bear was named Teddy and was used to entertain Corbett's children.
Black ears, said to be created using coal dust, gave Sooty a new name and a distinctive look. Sooty and Corbett went on to win the BBC TV show Talent Night.
A regular slot on the children's show Saturday Special followed and then the launch of The Sooty Show in 1955, which Corbett's son Matthew took over in 1976.
Since 1999, Cadell has been the one uttering the show's classic catchphrase: "Izzy whizzy let's get busy."
The affection that people have for Sooty came as no surprise to Cadell who said he "loved it", adding: "However, I will say that you can't rest on your laurels. You know, you can't just trade on former glories."
He said being Sooty's guardian means a lot of hard work but a lot of fun.
"I do feel that it's important to keep him relevant to today's generation to make sure that affection still exists when they become parents and they want to come to the theatres with their children.
"So I feel a duty of care. You know, the little bear survived 50 years before I was on the scene. And I want to make sure that he survives 50 years after I'm not on the scene, you know.
"It's more than a job. It's making sure that this little fella is here for everyone to enjoy for as long as possible."
Cadell said Sooty and Sweep are a "classic double act", and the entertainment comes from putting them in scenarios familiar to the audience.
"So you've got Sooty that's very clever but naughty and Sweep that's a bit of a fool, as much as we love him. So the shows kind of write themselves really."
The scenario for the 2023 tour is Sooty's 75th birthday party. Autumn UK dates have been announced with more shows to be announced for spring.
"What would Sooty do? He'd invite all his friends, he'd invite some star guests, and then everything would go wrong," Cadell told PA.
