“Hatching new scientists every day!”
Peep is a newly hatched chicken who goes on daily adventures with his friends Chirp the robin and Quack the duck. The pals live a large urban park they call "the big wide world" and is the setting for all their lessons. Peep learns specific science concepts on his travels, while the series also incorporates real kids playing and experimenting in their own big wide worlds.
