When four swamp creatures looking to cross a river come upon a log that would allow for precisely that, they can’t believe their luck. But a questionable tail adjacent to that log gives them second thoughts. Opossum believes it’s a sneaky tail and that they must pass it quietly. Squirrel thinks it’s a scary tail that can be cowed by intimidation. Rabbit decides it’s a mean tail that deserves a taste of its own medicine. As the critters exhaust approaches one by one, Mouse, the smallest of the lot, observes their folly and adjusts accordingly. But is it the mouse or the tail that will defy expectations?
