Hobart, Zeke and Alice come across Chester, a highly evolved yet tiny dog who speaks incessantly. Chester, a secret agent from the Planet Sirius II, is convinced he's in a prison ship and tries to organise a breakout with Hobart. Meanwhile Bob Santino sends the galaxy's best bounty hunter, Baba Ganoosh, to find and destroy the Valiant. Not only does Baba Ganoosh find the Valiant, he is confronted by his niece, Gemma. This could be his toughest mission ever.
