As the episode begins, we find Baby on the moon wearing an astronaut's helment. The Narrator greets the viewers and allows them to say hello to Baby. He says that today Baby is looking for Sophie but he doesn't see her. Sophie pops up in the distance behind Baby from under a crater. The Narrator asks the viewers if they see Sophie. Baby then sees her and is happy. The Narrator allows them to say hello to Sophie and then Baby and her wave to each other. Then Sophie goes back down. The Narrator asks where she has gone but Baby doesn't know. Sophie then pops from a crater that is closer to Baby. The Narrator asks the viewers again if they see Sophie. Baby sees her again and they wave. She goes back under and pops up from the crater next to Baby. She comes out and Baby gives Sophie a kiss in the air. Sophie then finds a rock and offers it to Baby. Baby takes the rock. Butterfly arrives and Baby and Sophie follow her. They begin to fly in space. They enjoy flying around. Then, the rock flies out of Baby's hand. The Narrator asks the viewers to help Baby get it. Baby flies over and gets the rock.They land back on the moon and find a rocket. They don't know what it is at first and the Narrator asks the viewers if they know what it is. He then says it's a rocket. Baby and Sophie start to float again. The Narrator helps them into the rocket and it takes off. Butterfly rides ont he front of the rocket. They look around as they fly through space. They then see a shooting star. The Narrator says he knows a song about a star and asks the viewers if they want to hear it. He then sings "Twinkle Twinkle Little Star." Baby and Sophie loved the song. They then begin to do the Go Baby! dance. They fly past a constellation of Butterfly as they dance. The Narrator allows the viewers to say bye-bye to Baby and Sophie and thanks them for their help.
