Josh and Elsie are invited to Bob's boat for an Aussie afternoon. Elsie is feeling shy and asks Grandpa to come along too. But as he hasn't been invited, he has to shrink and hide in Elsie's backpack.

Bob has made his guests a fantastic Aussie picnic and wants to play them an Aussie song on his musical boat, but it's not working. Then Bob decides to show the kids his lucky Aussie dollar, but he can't find it. As Bob starts hunting for his dollar all over the boat, Grandpa is nearly seen and Elsie has to hide him in Bob's didgeridoo.

Unfortunately, Bob tries to play the didgeridoo and blows Grandpa into a bucket of smelly prawn shells. And that's where Grandpa finds the lucky Aussie dollar! Show less
