Rababou is a little star world creature forcibly sent by Higenoshita to aid Comet into finding the prince of the Tambourine Star World. He can easily detect twinkles with his tail and can inflate himself to fly making him very useful for collecting star power. If he isnt exposed to the outside world he is hiding in Comets Twinkle Star. Even though Rababou appeals to others as a cute little toy he constantly nags Comet into staying on task but Comet only believes that he should go out and have some more fun. Rababou may order his princess around a lot but he truly cares for her as a friend and a princess. Rababou is one of the only people well in his case star world creature that Comet can confide her feelings in. Later Rababou falls in love with Spicas star world pet Rabapyon.
