Shelby and Watts are “Planetary Investigators”, aka detectives with an environmental focus in this first book of a new graphic novel series. Shelby, a fox with a notebook, is a budding detective while her friend, Watts, loves facts and encyclopedias. They are called upon to investigate the disappearance of shells on the beach. Fred, a hermit crab in a very tight shell, is frantic. He needs a new shell for a home and protection, but there are aren’t any to be found. His pals are in the same “pickle” (“in a difficult situation” as defined by Watts).

So, Shelby get to work tracking down the shell thief. They follow several clues, all of which are noted in Shelby’s notebook. And, Watts adds in relevant facts about the beach and its inhabitants. They discover the missing shells and the so-called thief – Arty, the rhino, who was collecting beach shells and didn’t know the havoc he was creating in the hermit crab world. Shelby and Watts give some great tips about saving the beach at the end of the story, like “leave the beach cleaner than when you found it”.

This simple nine chapter graphic novel is a nice transition story. It is much shorter than its 94 pages appear, with several single panel pages. Color is vibrant and text is accessible. Interesting facts about ocean creatures are interspersed throughout and do not interrupt the flow of the story. Recommended.
