Koa the koala lives on a small, cozy houseboat that rocks gently on the blue bay. He tends a little potted gum tree on the deck and hums soft songs as the sun warms the wood. One morning, Koa looks out at the sparkling water and wonders what adventures might drift by today.

He sets a cup of tea on the railing and decides to row to the nearby cove to see who he might meet.
