These are The Pup Star Patrol who actually are harmless puppies. Somebody must have turned Krypto the Superdog and the dog stars into the cute little puppies. And it was Mechanikat and Snooky Wookums who turned them into puppies with the puppifying ray which has a little Kryptonite on it. The only reason at the end of this episode Puppy Problems is that Delilah took the Puppifying Ray in her paws in the beginning of the episode Meet the Pup Stars so that the super puppies started their adventures in the city of metropolis. And the only way to do that is to gather every single playmate their size like The Supercat Fan Club, Robbie the Robin, Jimmy the Rat, Squirrel and Crow, Ignatius and Blaze. They may only be seen in the series "Adventures of the Super Puppies" and "Krypto the Superpup".
