Stretch-O-Mutt meets the Dog Stars for the first time and boy, is he excited to see real space heroes. But soon there's trouble as Mechanikat infects everyone on board, except Krypto and Stretch, with "space spots" virus and invades the ship. A Kryptonite ray keeps Krypto from stopping the invasion so it's Stretch to the rescue as he impersonates the Dog Stars in an attempt to fool Mechnikat. There are some funny scenes and the ending where the tables are turned on Mechanikat is clever.
Not a bad episode, and I like Stretch, but the formula of Krypto and/or Streaky losing their powers or being weakened by Kryptonite so they need Stretch's help is already getting a little old, at least to me. Stretch's strategy of impersonating the Dog Stars was also a little too close to the plot of 'Solar Specs' where he fooled Mechanikat and crew by impersonating the villains.
But it was fun to see the Dog Stars and I really enjoyed the initial scenes where the heroes meet for the first time. I still think Stretch has potential, they just need to find new things to do with him.
