I thought of this story when I was going to the dinosaur museum.

Brief Summary

Peter, Squawk, Leo, and Jennifer are a group of teenagers who are in the Mystery Shack. A group of highly intelligent kids that are always up to any case. However, the city has been overrun with mysterious dinosaurs but are they really what they seem? When everyone else steps out of the case it is time for amateur detectives Peter, Squawk, Leo, and Jennifer to show who really are the amateurs.
