Sand Bat

 Sand Bats were creatures that lived in the deserts of Bara Magna. They were 15 feet long and was known to pop out of the sand to both get a view of its surroundings and to hunt. The Sand Bat couldn't stay in sunlight for too long at risk of being incinerated. Mata Nui and Metus once fought a Sand Bat and defeated it on their way to Vulcanus.
