Dash is a little firefly. One of his wings is shorter than the other so he flies more slowly than everyone else, but that doesn't stop him getting where he wants to go. When he's happy, his bottom lights up! And he's happiest when he's eating custard and hanging out with his adoptive brother, Dribble the snail. Dribble is never in a hurry. He likes to invent things—and eat cabbage. He keeps all kinds of useful objects hidden inside his shell. They help to keep him out of trouble, which is never far away... Join our minibeast heroes on their first adventure as they foil a master criminal plot involving a crystal worm, ancient custard, a stolen Roboslug and some dastardly dung beetles.
