(Sorry I took this down earlier. I accidentally reviewed the wrong episode. My bad! Oof!)

Plot: Cole, Princess Vania, Master Wu, and the Lowly arrive at an ancient abandoned temple. Wu realizes it is The Heart Of the Mountain. The group discover an old abandoned Stone Mech and a mural of Cole's mother, Lilly. In the mural, she is depicted fighting the dragon, Grief-Bringer, using the Spinjitzu Burst. Wu tells Cole about the Burst - a powerful form of Spinjitzu which his mother studied.

Things I enjoyed:

- I like learning the legend of Lilly and the Spinjitsu Burst.

- The heart of the mountain looks really cool!

- The mech was awesome! I hope the rest of the ninja get elemental mechs eventually too!

- The animation where Fungus showed the other ninja was awesome!

- Cole's like "what do I do?" And Wu says "I don't know." 😂😂😂

- Wu is back to his old self again.

Things I didn't like:

- Corgran just running into the wall. 🙄

- Other than the mine cart scene, it was a lot of standing around.

Overall score: 8/10

Other than it not being very action-packed, I really enjoyed it. See you again soon!
