The event was held last week at the Lee Valley Athletics Centre in Edmonton, North London to raise money for children's charity Barnado's.
The 'Bounce for Barnardo's' event saw a new World Record set by 9-year-old Skylar Kelly for bouncing 50 metres on a spacehopper in the fastest time.
"When we found out about the event I couldn't wait to come down and get bouncing on my spacehopper," she said.
"I'm so happy I set the World Record and I've had the best day. I've also managed to raise some money for Barnardo's which is pretty cool as I feel like I've been able to help out kids that maybe don't get the opportunity to play on space hoppers."
Brazier, who attended with his sons, added: "I've had a really fun day - it's been the perfect family day out with Freddy and Bobby and all for a very worthy cause."
A Barnardo's spokesperson added: "We were thrilled to be able to partner with Mini Babybel to host the Bounce for Barnardo's event.
"The kids had an amazing time bouncing on their spacehoppers, and we raised money to help our work transforming the lives of more than 190,000 children and young people in the UK every year."
Mini Babybel is giving away 15,000 spacehoppers to those who collect four special packs of the cheese and enter the codes on the Babybel website. Money can be donated to Barnado's via Mini Babybel's fundraising page.
