Streaky finally meets the elusive Bird Wonder, who explains that Krypto and Bat Hound are missing, and suggests that Isis is behind it (in the beginning scene, you see them chase Isis and get caught). Apparently, Robbie came back from down South to find Bat Hound and learn from him some more (saying that no one takes him seriously). Isis has teamed up with Mechanikat and plans to send Krypto and Ace to him. Streaky gets captured as well (goes too close to the kryptonite by accident), and Robbie is forced to tackle Isis and rescue his friends.
Perhaps a bit too short. I would've liked to see Robbie in action more, but it really is nice to see him return (originally, he was thought to be a one-shot character, but not anymore). Worth a view, and you won't be disappointed. 9.8/10
