The four Twirlywoos - Great Big Hoo, Toodle-oo, Chickadee and Chick - have adventures both in the real world, and in their boat. They learn about a new concept each episode. Shy Peekaboo also lives on the boat, and joins in without the Twirlywoos knowing. The boat sometimes gets visitors, including the Stop Go Car and the Very Important Lady.
