"They're watumba bats, you big baby. They eat algae, insects, and fire, not Wookiees."
Han Solo to Chewbacca[src]

Watumba bats were flying animals that lived in nests. They ate fire, algae, insects, and rock dust. Glottalphibs considered them to be a great delicacy and liked to keep them, although this was at great risk to themselves as the bats would kill the Glottalphibs to eat their fire if enraged.
