A lost cowboy riding a seahorse might be looking for the ocean, which is what the other cowboy is providing directions towards. The ocean is what is big and blue, and because it's so big, it's difficult to miss. It's funny that the seahorse cowboy could find himself so far from the ocean because it would be hard to get this far without trying to.
