Ava the Postie discovers she's got a flat tyre on her bike, so rings Odd Job Austin to see if he can come and help. Odd Job Austin is hard at work in his workshop, but there seems to be a loud squeaking sound coming from somewhere. Austin thinks it's his saw that's squeaking, so he puts some oil on it. Next, Odd Job Austin takes his bike pump to Ava the Postie and helps fix her tyre, but there's no stopping the mysterious squeak. In fact, the squeak seems to be following him wherever he goes.
