Dexter is a typical 8-year-old boy: other than the fact he's a genius with an enormous secret laboratory complete with computers, experiments and machines hidden beyond his bedroom wall. Despite sneaking to the lab when he can, he still can't get away from his big sister, Dee Dee, who loves to dance her way into Dexter's well-ordered world, disrupting his inventions and annoying him beyond belief. They have sibling rivalry down to a science! less
