Star Watcher is an Apatosaurus louisae who is one of the Longnecks from Grandpa Longneck's stories. Every night, he'd climb to the top of a hill to look at the sky stars. But one night, the sky stars decided to come down out of the sky. They wanted to take a look at the Longneck who was always looking at them. They said hello to him and asked if he would like to visit them up in the sky.
At this point Saro interrupts, asking Grandpa Longneck "Are you sure that's how it happened? I'm not so sure you're telling that story right." and the rest of the story is not told.
