The teams make a splash with this episode's challenge: designing underwater robots!
They're making the robots for Super Duck Excursions, a tour company that uses amphibious vehicles -- that means they can go on land AND water. The robots should be designed to surprise and entertain the people on the tour. Think sea monsters with an engineering twist!
