Baba quickly dived back out of sight too.
Johnny peeked through the screening of bushes. His mother was riding toward the rock on Skorkin, the rhinosaur! This hideout was not very secret. Everybody on Venus knew about it. He stood up, and waved down to her.

His mother nodded and the big rhinosaur turned back toward the settlement.
