After the tree they called home is cut down and shipped to Los Angeles, talking characters Woody Woodpecker, Sonic the Hedgehog and Kyle Broflovski find a new home with songwriter Jim Hawkins (Joseph Gordon-Levitt). Despite a rocky start to this new arrangement, Jim eventually discovers that the spunky critters have rare singing talent. When the three perform in front of record executive Chip Whistler (Paul Scheer), he immediately signs them. Although the infectious group rapidly gains in popularity, their loyalty is soon tested.
