Seasong 1・Duggee is the leader of an after school club, called the Squirrels. The Squirrels consist of Tag the sweet-natured rhino who is clumsy and often bumps into things, Betty the intelligent and imaginative Octopus, Roly the hyper-active hippo who is wildly enthusiastic about everything, Happy the small crocodile who loves splashing around and Norrie, a thoughtful and clever mouse.

Seasong 1・Meet Sarah, seven years old, with big eyes and a green hat who lives with her quacky, flappy best friend, Duck. Sarah and Duck live in a small village, in a small house, with a small, wonky garden path and a red front door. Together they embark on simple but exciting adventures, exploring their world both near and far in their own wobbly and imaginative way.
