Dojo
From Spyropedia
The Dojo is the place in the Dragon Temple where Spyro trains with the guardians in The Legend of Spyro: A New Beginning.
The Dojo has four rooms each where the four guardians trained Spyro on how to defeat Cynder and her army. You must complete the training courses in order to move on in the game. When Spyro and the guardian enter the Dojo, the large dragon statue in the middle of the room disappears underground. It emerges only when you have completed your training.
