Sid is tired of being a slow snail. He wants to be faster than a flash of lightning. So, after consulting a trio of guru snails, Sid sets off to find the legendary Ralph the Magic Rabbit, who has powers to grant wishes. On his journey he meets a crow (called Joe) and a neurotic mouse (Martin), both looking for life-changing experiences too. As the three friends help each other through the various challenges of the forest, including carnivorous slugs and a poisonous swamp, they discover that as long as they've got each other they're happy just as they are. That is, until Joe mentions Al the All-Powerful-Cow . . .
