Six cadets from the Hubble Bubble Space Federation get sucked into a black hole and spit out on the other side of the universe. Rocketing through space in Henry, a sentient, simpleton, star-dust-eating spaceship that they discover, the “Hub Bubs” face countless challenges as they quest on the greatest adventure of them all, finding their way home.

While all from very different planets — who at one time were at war with one another — the Hub Bubs will come to accept and embrace their differences, learning that love, trust, and laughter are the most important things among friends.
