Dinosaurs do exist.
Especially when they have names like Ziggy, Rico, Rashawn, and Jerome - otherwise known as The Black Dinosaurs. Okay. They're not really dinosaurs; they're just a group of friends who've decided to start their own club. And, since all of the guys thought Rashawn's huge plastic Apatosaurus was cool, they decided to name the club after it.
It doesn't take long before the Black Dinosaurs are on the case, because something very strange is happening in their neighborhood. Someone has buried an old trunk near the secret club-house-and it's filled with bones. And someone has been writing weird notes and singing strange songs about bones rising again. What's going on?
Well, that's what the Black Dinosaurs want to know and they're determined to get to the bottom of the weirdness - no matter what!
