'I suppose not,' says Stobey. 'Tell us, Suzanne and Roger, why has an interplanetary space liner come to Super-Rock Playground. Aren't the regular ports for space liners in orbits above Io and Europa?'

'Well, yes,' Suzanne says. 'We're on our way to Europa to visit our uncle who's in charge of a space colony. The colonists are also people from Planet Earth.'

'The Captain of our space liner told us the port at the Europan colony is temporarily filled with other space liners,' Roger adds, 'so he brought our liner here for a couple of hours to wait until a mooring slot for us opens up there.'

'Right,' Suzanne adds. 'When we got here and saw this beautiful playground we asked the Captain if we could visit it for a while. As you see, he agreed, and here we are.'

'We're certainly glad you came,' Stobey says. 'We're heading for the
Midway. Would you like to join us?'

'Oh, yes,' says Roger, 'we sure would.'

'Yes, we would like to join you,' says Suzanne, 'and we thank you for the invitation. But we must be back aboard the space liner in two hours. Will you be sure that we don't miss getting back here in the parking block in time to lift off?'

Chug steps forward. He draws himself up to his full height, raises one spaghetti-thin arm to point upward, and speaks with a deep voice.

'It shall be my honor and my pleasure,' he says, 'to show you all the wonders of the Great Super-Rock Midway, and then to bring you back here in time to return to your space liner. I, Chug-a-lug the Hooten- Nanny, will be your guide.'

He proudly points at the brilliant, many-colored lights of the Super-Rock
Midway.
