Once, in an old rusty bin in an old rusty playground in an old empty park, there lived a little tortoise.
But Tortoise is lonely. He's never seen any other tortoises, and wonders where they could all be hiding.
Then, one day, he looks up at the night sky, and sees a million blinking lights winking at him.
"That must be where the other tortoises are - at the top of the sky! I wish I could join them."
But how can a little tortoise get to the top of the sky? And so begins a magical journey...
