Finny and Sammy the Seahorse visit their friend Oscar the Octopus for a play date. They promise to mind their manors and not leave a mess for Oscar and his dad Dr. Octopus to clean up. When playing as scientists and building a robot in Oscar’s room, Sammy and Finny get impatient. They start tinkering with the robot without Oscar, accidentally creating a mess-making machine! Finny and Sammy apologize for the mess. They all work together to clean up after themselves before it’s time to go home.
