The students in Dr. Cosmic's class take their lessons underwater when they're introduced to his latest invention, the SKWID--a special submarine that explores the ocean and looks like a real giant squid!

With the guidance of oceanographer Professor Fathom, the class embarks on an exploration of the deep sea. Their next assignment? Identify the smallest producers and consumers of the ocean.

But when a giant whale approaches the SKWID, mistaking it for an actual squid, the students must use their trusted scientific handbooks to find a way to escape the submarine and return to the undersea lab--before they become the whale's lunch!

Don't miss more from the Mad Scientist Academy series!--The Dinosaur Disaster, The Weather Disaster, and The Space Disaster.

"Dr. Cosmic is plainly a colleague of Ms. Frizzle [of The Magic School Bus], and the mix of pithy banter, tumultuous field-trip mishaps, and science fact is as familiar as it is winning. Fans of the Frizz will be dino-delighted. Mad fun." --Kirkus Reviews, starred review of Mad Scientist Academy: The Dinosaur Disaster
