When Pluto wandered into the solar system, it crossed Neptune's orbit and was held. Its moon came closer to Neptune and was captured completely. But Pluto, having a greater mass, didn't stick.

They had thin, trunklike bodies with two long, pencil-like branches that were used as arms. And the coconut objects were heads!
They circled the dome now, and Burl could see that each round blue knob had a central black spot that apparently
