Now that Mush -- the talking, cooking, educated dog from space -- is part of the Mangiaro household, Kelly wants to know more about the planet Growf-Woof-Woof, and how her dog came to Earth. When the two of them go on a picnic, (which Kelly prepares carefully under Mush's supervision), Kelly asks Mush about her past. Well, it's such a long story, says Mush...and soon, Kelly is hearing about Mush's old jazz band, The Hot Animals, and how they dealt with robbers who threatened to knock over their boss's jive joint!
