Get ready to make a splash! PEEP and the Big Wide World Quacks Apples is an iPhone game developed by WGBH Interactive. In this app, players help Quack, the hilariously quirky duck, roll apples into the pond for his fish museum. However, they must watch out for rabbit holes, as bunnies don't seem to share.

In Quacks Apples, kids can have as many tries as they need to perfect their route for getting Quack's apples to roll into the pond. The game encourages kids to practice the engineering design process integral to scientific thinking by testing and tweaking their designs until they succeed.

Players are unable to get rid of the sticks that block the apples, but they can tap on them to turn them in different directions and create a path for the apples to roll into the water. As players progress, each setup becomes a little harder, challenging their problem-solving skills.

PEEP and the Big Wide World Quacks Apples is a part of the animated series PEEP and the Big Wide World, which aims to teach science to preschoolers. With its wry humor, charming plotlines, and lovable characters, this game is designed to engage kids aged three to five years old.
