Ninjago: Assault On Ninjago City

ÖZET

Cole discovers that the stone mech is powered by elemental earth energy, and uses his powers to activate the mech. He straps the mech to the mine cars, and uses it like a crude rocket to blast the mine cars back up the track to the top of the mountain. Along the way, however, the magma monster arrives, and a desperate battle between Cole and the creature ensues.
