Ok after three guesses, none guessed right (even though F-22 posted a second response after his first one was incorrect, and partly my fault for not saying you don't get a second chance).
The answer is the Rainbowfaces from LBT 7. The little riddle makes sense...it was 500 points after all so I wasn't going to make it a cakewalk.

They might've been looking into the past or the future, we never really learned anything about them, and they looked so much alike they could've been a clone of the other if not for the different voices.
Oh well, update them scores Tim. Tails, pick another category and point value.
