Quack hides, you seek! In this Where's Quack app, the hilariously quirky Quack hides in a number of different locations. In each location, different hiding places change the way Quack's voice sounds. Is he muffled, or maybe far away? Is he down a hole, or underwater? Players can help Peep find Quack by listening as they look for him. There are also a few surprises along the way!

The Where's Quack app was designed to be a digital version of hide-and-seek. If the player finds Quack, he'll hide again. (Ducks are excellent hiders, as Quack himself modestly states.)

The PEEP and the Big Wide World Where's Quack? app was produced by WGBH and the producers of PEEP and the Big Wide World. The animated series PEEP and the Big Wide World gives wings to the innovative idea of teaching science to preschoolers. Wry and distinctive visual humor, charming plotlines, and lovable characters combine with a comprehensive science curriculum to attract and engage kids three to five years old.
