Ninjago: Masters of Spinjitzu: Season 5 Episode 4

The Temple on Haunted Hill

The Ninja hear of another way to learn Airjitzu – from the ghost of Sensei Yang at his haunted temple – but there’s a warning; if you are trapped in it by sunrise, you will become a ghost, too. Meanwhile, doubting she’s a Water Ninja, Nya quits her training to take Ronan to her Samurai X cave…but has a run in with Moro.
