One of the things that has always bugged me about the otherwise excellent "Thundercats Ho!" is the giant plot hole of the Thunderians being held at Fire Rock Mountain. Lion-O says to Tygra and Cheetara that he is going to confront Mumm-Ra at his pyramid to learn what Mumm-Ra has planned for the Thunderians. When Lion-O goes to the pyramid, he doesn't talk to anyone. When he frees himself from the mummy wrappings in Part IV, he somehow just knows to head to Fire Rock Mountain. Lame. But check out this book and tape set: There is a very brief explanation given around the 12 minute mark, right after Cheetara and Tygra save Panthro from being pinned under the tank. Panthro tells them that the Mutants headed toward Fire Rock Mountain, and he surmises that is where their compatriots are being held. Granted, this still does not explain how Lion-O learned of it, but at least it puts the information into the hands of the heroes somewhat. So I am left wondering; Was the relevant dialogue present in the script that the book and tape people adapted from, and somehow it was edited out of the episode, or did the adapter for the book on tape notice this giant plot hole and hastily write in an explanation? What do you all think?
