Between a Rock and a Wet Place

Zack and Rex are exploring a trail near Zerby Town Lake when Zack falls down a steep hill and lands on a small beach. The hill is too steep to climb up and the beach is blocked at both ends, preventing Zack from being able to get back. Zack and Rex try, try again to figure out a way to get Zack off the beach. Rex gets a rope and tries to pull Zack up, but Zack keeps getting caught and Rex can't pull him. While Rex is off looking for answers, Fran the Ferry comes by and asks Zack what he's up to. That's when Zack realizes that he can get off the beach by riding on the water - on Fran!
