Prince William has two "very cheeky" children at home!

In the new ITV documentary Prince William: A Planet for Us All, the royal dad surprised a group of schoolchildren who built a bug hotel, cleverly dubbed "Bugingham Palace." In addition to discussing the importance of insects on the environment, the children were full of questions about William's own kids: Prince George, 7, Princess Charlotte, 5, and Prince Louis, 2.

"Is Princess Charlotte cheekier than Prince George?" asked one child.

"No, they're about as cheeky as each other," William, 38, answered. "They're very cheeky."

Another student asked William if George had taught the family how to do the floss dance.

"No, Charlotte can floss," William replied, noting that their daughter had mastered it at the age of 4 and that his wife could also do the popular dance style. "Catherine can floss, but I can't. It's, it's like a really horrible film to watch me floss."

In the documentary, which premiered January 14 on discovery+ streaming service after airing in the U.K. in October, William said he owes it to young people to help their "voices be heard."

"That generational gap has to be bridged somehow," the royal explained. "I feel it is my duty and our collective responsibility to leave our planet in a stronger position for our children."

Luckily, Prince William knows exactly how to fix the perfect "cuppa."

"At the end of the day, she's in training to be a future Queen, but honestly you would never know it," a source close to Kate previously told PEOPLE. "If you go round to her house, you get a cup of tea, and it's often William who makes it! It's a lovely, welcoming house, not a fancy, stuffy palace in any way."
