Thundercats Odcinek 25: What Lies Above, Part 1

The ThunderCats' search for the next stone leads them high above Thundera to the floating bird city of Avista. The Birds possess the Tech Stone but have no intention of handing it over to the Cats as it's the power source for their city. The stakes are high when Tygra challenges the birds' leader, Vultar, to an aerial battle where the winner gets the stone.
