STAR Labs has invented a new robot, Alfie, and the guard dogs are in charge of making sure it stays safe. One of them, named Buddy, is a care-free dog who slacks off in some ways. He accidentally pushes his ball into another room after the other guard dogs leave, and he gives chase to it, only to fall into a vat of elastic compound chemicals. Before the others can reach him, the door to the labs slams shut, and two theives are there to steal the robot. Superdog is flying by, and he hears Buddy's howling. Before he can make it to him, he's submerged, and it becomes apparent when he gets out that he's now a "Stretch-O-Mutt". He now has to help Krypto recover the stolen robot, which was stolen by the theives and hidden in an ice-cream factory. Here, he puts his newfound powers to work, stretching and morphing all over the place. They get back the robot with little trouble.
A fine intro to Stretch-O-Mutt, and by the looks of things, he'll be used later on in the season (judging by the new opening to the show). I would've liked to see a little more action from Stretch (more forming and stretching). He only showed us a bit of what he could really do. 9.8/10
