Darcy Dolphin and friends are back for some more underwater adventures! In the third book of the series Darcy joins the Sea Trouts, whose motto is 'Lend a Fin'. But Darcy's attempts to be helpful don't exactly go swimmingly... and soon there's chaos at the pet exercise class, an extremely grumpy resident at the Retired Sharks home and a plankton on the run! Can Darcy sort it all out and still have time to throw Ozzie Octopus the best birthday party ever?

The third in a brilliantly funny new illustrated fiction series for boys and girls aged 6 years +. Perfect for fans of The Unbelievable Top Secret Diary of Pig by Emer Stamp, Barry Loser, the Wigglesbottom Primary series by Pamela Butchart and the Daisy books.
