About this season
A naive young Dolphin named Jim finds himself in charge of navigating the first-ever submarine on wheels! Jim is joined by his motley crew of underwater buddies as they journey across land and sea. Their water-filled tube has left the ocean to seek out an unlikely destination, the pristine waters of ‘Fishland.’ Luckily, with no set route in sight, their journey promises to be a long and winding one.
