|Mountain of a Million Steps|
When Nya discovered that the Serpentine had been moving underground to avoid detection by the Ninja, she pinpointed their main base inside the Constrictai Tomb. With Pythor already on the trail of the fourth and final Fangblade, the Ninja, Nya, and Sensei Wu go to the Mountain of a Million Steps to retrieve the three Fangblades already collected by the Serpentine.
After the Ninja were captured by Pythor, Lloyd donned the Green Ninja suit for the first time and climbed the Mountain of a Million Steps to aid his friends. Shortly after his son's entrance into the fortress, Lord Garmadon sent the Skulkin Army up the mountain to reinforce the Ninja.
