The campaign intends to raise £1m over three years for children with complex healthcare conditions, or life-limiting and life-threatening illnesses, who use the Docklands-based hospice’s service.
Lord Sugar’s advisor Nick Hewer agreed to be filmed for the Facebook campaign, in which he is interviewed by a 12-inch glove puppet called Harry.
Kate Walsh, the runner-up in the 2009 series and presenter of 'Live at Studio 5', was also interviewed by the puppet as part of the hospice’s Harry's Million campaign.
Harry the puppet is based on Harry Singh, a young adult at Richard House. The puppet was created by the children of Richard House with the help of Clapham-based Absolutely Cuckoo, the people behind the CBeebies children's programme 'Waybuloo'.
The real Harry has received care from Richard House for the past nine years and is now employed one day a week by the hospice.
In the film Hewer reveals his hobby of collecting vintage tractors and speaks about the attributes a contestant should have to win a place on 'The Apprentice'.
He said: "The chances of you getting through (to 'The Apprentice') depend on the creativity of your application form, and how brilliant you are in the audition."
