Tilda is so excited to show Binky and Harry what a superstar swimmer she is, with her splashy splashes and fishy flips. But when she realises she can't swim properly, Tilda is embuzzled. That's right, embarrassed and puzzled! Maybe Tilda will feel better if she teaches her friends something actually fun like cartwheeling! Tilda's cartwheel class is super fun, until it rolls out of control.
