This coloring book depicts two characters from the Lego Ninjago series representing the sinister Snakes. One of them has a long serpentine body with a dull but sullen face and holds a sharp weapon in his hands. The second character, also snake-like but more angular and with spikes on his head, prepares to attack with battles. Both forces gather in a real duel, creating a sense of intense struggle between good and evil in the world of Ninjago.
