Sherman and the crew are back, living life in their beloved lagoon as they deal with problems that sound all too familiar to us land-dwellers. But they're not the only ones to call this corner of the tropics their home. There's Arturo, the ninja lanternshark who briefly becomes Sherman's guru and mentor. Boris the fish-eating spider--who's really not so bad once you get to know him. A gang of obnoxiously sassy water bears. And one undersea spaghetti monster with a wit that cuts deeper than the Mariana Trench.
