The plot for this space adventure involved Rowlf travelling to planets and solar systems far outside of our own. On one such planet, everything is on wheels -- people, animals, trees, shopping centers, etc. Inhabitants of the planet have to roll on by from east to west because the nights are so cold, so they keep moving to stay in the sun. Rowlf gets tired of walking, especially when he has to push his rocket ship in a wheel barrow. Sometimes he gets tired and sits to watch the world go by -- at which time a song cue would be called for.
Throughout his journeys, Rowlf encounters many trials and tribulations and in one case, manages to save an entire civilization of Fneebs from the Horrendous Fneeb-Eating Ka-Zunch.
A script outline is held in the files of the Jim Henson Company Archives.
