Scooby Doo! And Guess Who? - Season 1

Our Shaggy is a bit of a Beatnik poet (but only when no one is around), and Scooby is so proud that he enters Shaggy into a poetry slam contest in Central Park. But, when Shaggy finds out he's going up against famous singer-songwriter HALSEY, he just about freaks. He freaks even more when the poetry slam is attacked by a horrible gator-man-monster from the New York City sewers below!
