Are you ready to Stash some Trash? PEEP and the Big Wide World Trash Stash is an iPhone game developed by WGBH Interactive. In this app, kids get to help Chirp, the plucky robin, make order of her world by sorting objects. The game starts with simple sets of colors and gradually progresses to more complex sets like Things You Can Eat and Metal Things.

One interesting aspect of the game is that objects can fall into multiple sets, adding an extra challenge for players. Additionally, older kids can try to guess the set before it's announced by watching the items being hurled by Raccoon.
