Rocky, Colt and Tum Tum are surrounded by about 50 ninjas with guns. They surrender. Then their grandpa jumps from an overhead walkway in front of them, and the kids immediately jump back into fighting position because Grandpa is so awesome that he just evened the odds.
Just the fact that until the ninjas pulled out the guns, three kids had defeated an entire room full of trained ninjas.
Rocky's gravity-defying, game winning slam dunk. While Colt just steps back and watches because he knows what's coming.
