In this episode, Ollie and his friends find themselves up to their necks in water trying to interview one Jean Paul Salmondo, an out-of-the-norm salmon committed to going against everything ? it?s just that going against the current is his thing. Right alongside Salmondo, they?ll make a crazy journey that will take them from the sea to the river where he was born.  Along the way our friends will find out about the different kinds of fish from their types of skeletons, they?ll hide with the rock fish and they?ll watch along with a hungry lamprey ready to gobble up whoever crosses his path. What are batipelagicic fish? What is the largest fish in the world? Why are salmon?s scales studied? What do they use their sense of smell for? Discover the answers to these questions and much more diving down with our friend in this wacky journey against the current.
