What the team did for colors in their Good Night, Sweet Butterflies, they now do for sound in Buzz-Buzz, Busy Bees: An Animal Sounds Book by Dawn Bentley, illus. by Heather Cahoon. Beginning with nine bees, when each sturdy page is turned, a fuzzy bee, peeking through a die-cut hole, flits off the page. Various barnyard animals entreat the bees to stay, but the response is always the same: "" `Oink-Oink!' says Pig. `Would you like to have some fun?' `Buzz-Buzz!' says Bee. `I really have to run!' "" When the last page is turned, a cacophonous buzz greets readers.
