Talking of annoying sidekicks, it always bugged me that they'd even brought Snarf with them to Third Earth - he (and presumably the whole race) are clearly the most annoying beings in the whole of the cosmos - so why not take the oppurtunity of the end of your world to rid yourself of the critters once and for all? Countless thousands of species must have perished in the cataclysm that the Thundercats fled from, and out of all of those, they went and saved a Snarf. Yeah, good choice there guys.
