Nick Bazebahl and the Wormhole Tunnels

In book 3 both Nick and Samantha get a chance to create their own stories. The theme is science fiction.

They slide through the first tunnel and into Samantha's story on a far distant planet. She has invented a Prince Charming who resides in a land of strange animals, but he is even stranger still and covered with boogers. When his zombie-like behavior creeps them out they escape down a wishing well.

They slide through wormhole tunnels into a space ship designed totally by Nick's thoughts. When he lets his imagination run wild Samantha is both impressed and afraid. Extraordinary things can happen in outer space.
