The Twirlywoos are watching some children collecting shells on a beach. The Twirlywoos decide they'd like to try collecting shells too - but it's not long before they start collecting lots of other things they find on the beach. Then, back on the Big Red Boat, the Twirlywoos get a visit from the Robot, but there's a mishap and the Twirlywoos find themselves collecting all of his nuts, bolts and cogs!
