The Lego Group, a popular Danish toy company, produces coloring pages based on its popular television show "Ninjago: Masters of Spinjitzu." These coloring pages are available at several websites, including HealthyChild, BestColoringPagesForKids and the Lego website itself.
"Ninjago: Masters of Spinjitzu" is an animated television series that follows the adventures of four Lego ninjas in an action-packed world. The basis of the show is actually an earlier series of action figures that the Lego Company created for its children's toy line. The coloring pages produced by Lego often depict either the four ninjas in various action poses or enemies and rivals of the foursome, such as Ninjago snakes and dragons.
