Aimed at babies and toddlers, The Twirlywoos (Great BigHoo, Toodloo, Chickedy and Chick) are ever curious as they adventure out of their big red boat and into the real world. They discover new concepts such as "going down the stairs" or "more and more" by watching and learning from humans. When they try to copy and help out, they always get a bit too enthusiastic and cause a bit of chaos.
