Mark and the Cetacean crew receive word of an unusual shipwreck on the ocean floor, and set out to investigate. What awaits them is an underwater robot created by Mr. Schubert, who is more than happen for the Cetacean to find it: it descended to a depth at which it no longer obeyed his remote commands, and only the Cetacean has the abiity to retrieve it…if Mark can disarm the robot, which fires an underwater laser at anything that moves. But what was the robot looking for on the ocean floor, and why is Schubert so certain that he’ll be able to get it back?
