Recognise these guys? It's Wenlock and Mandeville the official mascots for the London 2012 Olympic and Paralympic Games.
Since their launch in 2010, they've been on a journey around the UK, encouraging children to take up sport. Now they've got a new animated adventure to get you involved.
Adventures On A Rainbow has been written by top author Michael Morpurgo and includes animations of some of Britain's biggest 2012 hopefuls, like BMX cyclist Shanaze Reade.
Mandeville takes on Paralympic swimming champion Ellie Simmonds in the pool, but soon struggles to keep up.
Ellie said she was thrilled to become a cartoon character: "I really think it is amazing. I love it. It's cool and it's got nice eyelashes."
World champion diver Tom Daley tries to teach Wenlock how to dive in the short film, that's being shown to school kids across the UK.
Triple jump champion Phillips Idowu said he thinks his animation is really cool. "It is a great piece and I feel honoured to be part of it," he said.
Adventures on a Rainbow was released on 1 March 2011, and is being shown to school kids across the UK.
