Fifteen pupils from the Kickfit Martial Arts school, Slough, have taken part in a performance at Legoland to kick start the Ninjago tour.
To compete in the Spinjitzu Challenge, martial arts schools around the country will have to create and perform a two-minute ninja routine at one of the roadshow stops.
The competition will be judged by Lego and its media partner DC Thomson. The final eight contenders will then battle to win the title of Master Spinner and become an official Ninjago Brand Ambassador.
On the tour stops, children will get the chance to meet other Ninjago fans and interact with the brand via the spinning tournaments, competitions, giveaways and the Lego Ninjago video games.
