Calvin Coconut / Salisbury, Graham

Calvin and his friends have the opportunity to earn some money by appearing as extras in a zombie movie being filmed on a nearby beach.

When Calvin gets a school assignment to do some original research, he decides to investigate his dog's stinky breath and ends up learning about more than just smells.

New fears for fourth-grader Calvin include a school bully named Tito and the return of his estranged father, rock star Little Johnny Coconut.
