Ninja Tortoises are a type of Ninjago wildlife found in the Mountains of Impossible Height. They can be identified by their smooth, rock-like shells, their long necks, and their wrinkled, aged-looking faces.
Ninja Tortoises are described as knowing literally everything, making them the wisest of all animals. They are also more than willing to share their secrets with curious visitors. Unfortunately, the extent of a Ninja Tortoise's knowledge is only matched by the slowness of its speech - on average, it will utter a single word every year.
The wisest of all Ninjago animals, Ninja Tortoises know everything. So, if you want to know the secrets of the universe, just ask them... but be prepared to wait, because each word they say takes a year to come out of its shell.[link unavailable]
