Sure!
The rainbow faces: Now, I'm sure many of you were irritated by their alien exodus, myself included. But they are actually some of my favourite characters. Due to the way they were speaking, they could have easily been terrestrial creatures, but were a hyperintelligent higher species dreaming on space exploration. The way they talked about 'Beyond the Mysterious Beyond' seemed more to me that they were dreaming of living there rather than they actually did.
In my mind, they are, in a sense, hyperintelligent dinosauroids as supposed to aliens.
Of course, their extreme intelligence and resourcefulness can be useful, but what if there was an EVIL rainbow face with sinister intentions? Something to think about...
