Arburian Pelarota

The Arburian Pelarota is a generally peaceful creature that is now extinct after a massive tick-like insectoid destroyed their homeworld. Typically slow, clumsy, and awkward, the Pelarota's soft flesh is covered by several exo-plates that fit together to form a nearly invulnerable shell. When at play or when confronted by aggression, the Pelarota can roll up into a giant ball, and with their tremendous mass, ricochet at incredibly high speeds. They are often confused for the similar Vulpinic Tortugan.

Evolution
after evolution the Arburian Pelarota skin color become bluish and contain the ability to extract spikes from they shell.but because they are extincted this form will not be possible to happen naturally.
