Ninja Squirrels are a type of wildlife in the world of Ninjago. Found on the Mountains of Impossible Height, they appear to be similar to real-world squirrels, but are described as being faster, stronger, and generally superior in every way. Their apparent ninja prowess manifests in their ability to run up any surface, as well as their ability to wield Ninja Acorns as deadly and accurate projectiles called "Shurike-nuts".
Like regular squirrels, only Ninja. This means they're faster, stronger, and better than all the other non-ninja squirrels. As masters of the Squirly Arts, Ninja Squirrels can run up any surface, and their flying Shurike-nuts never miss.
