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...

Dribble has a new invention: a Bubbler (made from superpowered midge farts), perfect for making fizzy drinks. Cool Nat promises to trial the invention in Grottibottigan's Juice Bar if the bros fetch him some seaweed from Bogbrush-on-Sea...

But the treacherous pirate Captain Slugbeard is rumoured to have buried his treasure on the very beach they're going to. And he's placed a terrible curse of bad luck upon anyone who tries to nab his loot.

At their hotel, the bros run into the naughty Dung Heap Gang, who are keen to sniff out the treasure. With the help of Dribble's latest invention, can Dribble and Dash beat the beetles and escape the curse. or will they fall into the clutches of pirates? And will Prudence the prawn - creepie crawlie of the sea - and Big Steve the sardine prove to be friends or foes?
