As Tygra, Snarf, and the Powerpuff Girls continue on their quest to help rescue the ThunderCats from the plague of mysterious crystal entities infesting Third Earth, their little fellowship is gaining more allies with each crystal-possessed adversary they defeat — but the strain is wearing on the three Titans of Townsville, who don’t have their accustomed powers to fall back on. Fortunately, they’ve just been joined by a newly liberated Cheetara, who provides a much-needed boost to morale just as the party enters the beau- tiful but treacherous Crystal Canyon. What they find there takes everyone by surprise — especially Blossom, Bubbles, and Buttercup, who have probably never even heard of the Lunateks!
