It's rainy and cold, and Albie's so tired that he doesn't want to go
swimming. But when Albie dives into the pool he finds himself swallowed
by a shark-shaped submarine! He realises these won't be any swimming
lessons because this is a pirate pool! Join Albie as he goes on a
underwater treasure hunt, meets scary underwater creatures and makes
some pirate friends - swimming has never been so much fun!
