Set in and around a pond, a bush, and a tin can, the show follows a newly hatched chicken named Peep, and his friends Chirp and Quack (a robin and a duck), on their daily adventures. Surrounding them is a large urban park - a place of great wonder and mystery, a place they are forever eager to explore, a place they call "the big wide world." Each half-hour episode contains two stories which highlight specific science concepts, plus two live-action shorts presenting real kids playing and experimenting with these concepts in their own big wide worlds.
It's winter, it's blah, and everything looks dead. Can Peep, Quack, and Chirp survive until spring?/Peep discovers his inner bounce when he encounters a frog, a mattress, and a jack-in-the-box.
Lynn visits an Ontatio lamb farm and learns the ropes. Delve into the colonization movement, an effort that sprang to life in the 1810s to send black people from America to Africa.

Afraid that the sun has forgotten to rise, Peep and Quack are relieved when they discover a flashlight./Peep and Chirp get lost, but use a range of familiar-and annoying-sounds to find their way home.

Newton the turtle has a series of excellent adventures involving a puddle, some dandelion fluff, and a very spooky cracker box./Peep discovers the answer to that ancient conundrum: "Why did the chicken cross the road?"
Peep's first encounter with thunder and lightning makes for a wet and tumultuous day./After falling into a rabbit hole and meeting three fuzzy bunnies, Peep decides to try life underground.
