The dragon slug, Kermit.
Kermit was a Dragon Slug captured on Hoth by Lil'Bacca, the one-eyed ewok. During a lumni lichen harvesting operation conducted by Twin Suns Transport Services in the caverns beneath Echo Base, a ferocious dragon slug attacked the company's employees. Lil'Bacca, being the bravest of all the ewoks present, wrestled the creature to the ground with his own two hands. After capturing it, Lil'Bacca named the fire breathing beast, Kermit. Nowadays both Lil'Bacca and Kermit are practically inseparable.
