One of the indigenous races encountered by the ThunderCats upon their arrival on Third Earth, the Wollos are a gentle, pacifistic race whose small size and lack of warrior ways makes them an easy target not just for Mumm-Ra and the Mutants but also for other hostile races on Third Earth.
Although instinctively the Wollos would appear to be quite fearful, they are nevertheless quick to befriend the ThunderCats, and the friendship and cooperation between the two races helps the ThunderCats to feel truly at home on their adopted planet.
