Testux are a predatory species from the planet Litorna.
Testux look like giant turtles with spiked tails and a reinforced rocky shell. They have strong beaks.
Each Testux has its own shell pattern.
Testux hunt on Cancerpei by pretending to be rocks. They use their tails to shock the prey or their tongues to capture it.
Their rocky shell is also very hard, so Cancerpei can't break it.
Testux's eyes are its weak point, and they can get stunned if aimed in the eyes.
Testudo is Latin for "Turtle".
