Maisy's a little nervous ...today she is going on her very first swimming lesson. There's lots of hustle and bustle in the changing room and - wow! - the pool looks SO big and it's ever so splish-splashy! Luckily, Eddie and Tallulah have come along too and they all have a great swimming teacher called Poppy, the hippo. Everyone has lots to learn, including floating, kicking and blowing bubbles, but it's a LOT of fun!
