Krypto comes back from his villain patrol without having anything interesting happen. Kevin and his family are gone, so he goes down to his rocket, and finds Bathound hiding. Ace recounts his story of how a robin he saved, named Robby, has decided to tag along and be his partner. However, he messes Ace up every time he tries to help, so Ace told him to go gather information, while Ace ran and hid where he thought Robby wouldn't find him. Krypto tells him he's overreacting, and when he turns on the lights, Robby's right there. Ace tries to get some time alone, but Robby insists that they talk. One of the pidgeons in Gotham said that the Joker's hyenas are in Metropolis, and are stealing pillowcases to hold other stolen apparel in. Krypto and Ace try to stop them without Robby, who gets Ace in trouble once again, while Krypto is out cold by kryptonite dust (an excellent use of kryptonite, and quite inventive). Bud and Lou put Ace on a giant spring, shooting him sky high while both him and Robby are stuck in a pillowcase. Robby uses his beak to tear it open, and the two of them save Krypto and catch the hyenas. Robby acknowledges that he no longer owes Bathound anymore, so he leaves to fight crime on his own.
I didn't find much wrong with this episode...in fact, nothing wrong at all, other than a problem with matching up voice recordings and animation. In an opening scene, Krypto talks, but his mouth only moves and no words come out of it until a second later. Still, enjoyable, and worth watching a few times. 9.7/10
