"Kids love ninjas. It's a sad fact of life."
LEGO is already priming its audiences for its The LEGO Movie spin-off, LEGO Ninjago, with a first glimpse at The Green Ninja in action.
The spot, titled Enter the Ninjago, has been released as an extra on The LEGO Movie DVD & Blu-ray, which hit shelves earlier this week.
The clip sees The President of Hollywood turn up to inform Emmet that they are adding Ninjas to The LEGO Movie because "kids love ninjas. It's a sad fact of life."
The LEGO Ninjago movie will not hit cinemas for another couple of years, with a release date still to be confirmed.
