He then asked the viewers to help save Christmas by defeating villains who had stolen Santa’s presents, with the children completed challenges during a Heroes and Villains-themed party.
He added: “I hear from Sharky and George that there are five villains that you guys need to stop from ruining Christmas. So, use your teamwork, your brains and your brawn to make sure that you do exactly that.
“Find them and don’t let them ruin Christmas, okay?
“At the same time, Christmas is a time we will miss our loved ones really, really badly. And that’s okay.
”But at the same time, it can be possible to feel guilty for having fun without our parents. But I am here to assure you that our parents always want us to have fun, okay?
”So don’t feel guilty – you’re allowed to have the best time ever, especially with this Scotty’s Little Soldiers community.”
And in the middle of the sentence: “So, go out there and have the best time, and...” – he removed his mask to reveal his face: “Merry Christmas.”

The dad-of-two, who shares son Alfie, 3, and 17-month-old Lilibet with wife Meghan Markle, Duchess of Sussex, 41, had partnered with the charity in November and he wrote to the children for Remembrance Day.
In 2019, he also dressed up for the charity, wearing a Santa outfit complete with a long white beard.
