Episode Title:
Peak-a-Boo.
Episode Description:
The ninja must travel to the Cloud Kingdom for a sword that will show their enemy's next move, giving them a huge advantage. To get there, they must climb the tallest mountain in Ninjago and jump into a cyclone that passes over the top of the mountain to get to the Cloud Kingdom. Halfway there, the ninja discover some tracks left by Morro's stolen mech, and realize that he is headed to Cloud Kingdom for the sword as well, so they try and pick up the pace. During an avalanche, Cole accepts being a ghost, and doing so, saves his 'brothers' from the avalanche. Afterwards, he finds out some neat tricks as a ghost to help him and his 'brothers' beat Morro. They get to the Cloud Kingdom first by using Airjitsu successfully and Morro get's there just in time to see the Ninja leave for the Cloud Kingdom, and his window of oppourtunity to get there close. Back at the Bounty, Sensei captures a ghost who fell off the mountain during a fight for answers.
