Snake Surprise!

When a boat is close to crashing into the yacht that is Mimi's home, the kids head out in a dinghy to avert disaster. They find that the boat's driver - rather than being a ghost - has been poisoned. And Jack, Lachlan and Mimi are off on an adventure that they never saw coming, involving saving koalas, seeing pet snakes and the promise of a lifetime of pancakes.
