It was spring in Sidney Snail's garden and all the snails were coming out of hibernation. They were taking part in their "Happy Wake Up" celebrations and there was much fun and excitement in the snail community.
The previous spring, Sidney had been incredibly lonely and had no friends at all. But since then, he had discovered a whole new world with lots of lovely snails just like him all doing lots of fun things together.
Sidney had many friends now but he didn't feel completely happy. He still longed to have adventures and to see the world outside the garden. With the help of his friend Drake, Sidney leaves the garden and encounters long-necked Monsters, the Terroriser and the Crusher beast.
But exciting adventures are not always what they seem and Sidney begins to think he will never be able to get back home to his garden and friends...
