Full is the pilot and the very first episode of Twirlywoos.
We are introduced to the Twirlywoos as they wave hi to the audience. Following this, the Twirlywoos visit a kitchen and fill up lots of items with water. At home, they have watermelon fruit tea until they are full. Then they hear the signal coming and run to the Twirlyring. They say bye-bye and the Big Red Boat sails back to the horizon, ending the episode.
- This is the first episode to be directed by Nigel P. Harris.
- This marks the first appearance of the Twirlywoos, Great Big-Hoo, Toodlo, Chickadee and Chick, and Peekaboo.
