Well, thanks to the "space spots" virus, all of the Dog Stars (save Mammoth Mutt for not being in this episode, as well as Krypto and Stretch-O-Mutt) are incapacitated, and Mechanikat invades the ship. To make things worse, he uses a kryptonite ray to strike the ship and keep Krypto powerless. Stretch-O-Mutt, being the only one who can fight, molds his body and pretends to be the Dog Stars in order to convince Mechanikat of his mistake of invading the ship. Soon, however, he figures out his charade, but Bulldog accidentally spreads the germs to Mechanikat and Snooky, driving them off.
We all knew it would come. Stretch-O-Mutt finally meets the Dog Stars. Only...he didn't really get to use all of the Dog Stars' forms to their full advantage, which I would've loved to see. But an excellent episode marking future episodes to come. 9.9/10
