Top of the Sky: Nick, Sally and Cat are playing with their toy rocket. Using the Cat's 'Whoa-Look-At-It-Go-Launcher,' he shoots the rocket up up and up! But now they need to go find it. Off to the top of the sky! They pass the treetops, and the mountains. Where is the top of the sky? They keep going higher until they're in space! They meet Audrey the Astronaut who explains that there is no top to the sky. The sky turns into space and space goes on forever! Just when the kids think their rocket is lost, they find it in Audrey's space station. Though they can't launch their rocket to the top of the sky, launching it to the moon is just as cool! Jiggle Bones: Nick and Sally are wiggling and jiggling like the jelly mould in front of them. But they can't quite widdle the same way. How come? Bones, of course! announces the Cat. Bones keep their bodies from being wiggly and jiggle. But why do they need bones? A visit to Dr. Giggles will answer that question! They learn about the big strong bones that help us stand and walk, the small bones that help us bend and move, and all the important bones that help protect our squishy bits. Even though they won't let you wiggle and jiggle like jelly, bones are important!
