It's an all-out Zack attack as the Black Ranger takes on the villainy of Rita Repulsa and Lord Zedd in two exciting episodes! Adventure 1: It's the Black Ranger's birthday and everyone has a gift ... even Rita Repulsa. She's sent a new monster -- the Dark Knight -- to say happy birthday, Zack. Will the Power Rangers be able to band together to blow out the candles on this gift? Adventure 2: Billy and Zack find some cool new sunglasses, but there's a problem -- their fellow Power Rangers suddenly look like Putties, and Billy and Zack are ready to attack. Even worse, Lord Zedd has sent a fire-breathing monster, the Salaguana, to take on Trini, Jason, and Kimberly. Does the Black Ranger have nothing but putty on the brain, or will he and Billy come to their senses in time to help their friends?.
