We're Betting It All on Tuna

Synopsis

Lucy had so much fun with the tuna-carving show during the cooking showdown that she wants to do it again, and presses Burton to "build me a tuna detector!" But Berecca points out that you can't catch tuna without heading out to open water by boat, so Lucy goes to the fishing port to get a fisherman to take her aboard. There she meets Moby, a veteran fisherman. Will the two of them manage to land a tuna!?
