Teen Titans

S02:E02 - Every Dog Has His Day

A mysterious flying saucer chases a strange, green alien dog that has traveled to Earth. But when the alien dog bumps into the ever-changing Beast Boy (who's now a green dog hanging out at the dog park), the flying saucer accidentally abducts the wrong pooch. And when the Titans spot the alien canine, they mistakenly think it's Beast Boy! Can the teen heroes clear up the confusion before the alien ship carts Beast Boy off to the far side of the galaxy?
