Bob has gone away for a few days and Mr Whoops has been looking after his boat. He wants to clean the boat before Bob returns and asks Josh to help him. Unfortunately, Great Aunt Loretta announces that she'll join them. Grandpa tries to come too but is told he's not allowed. So he shrinks!

At the boat, Mr Whoops soon starts having little accidents. Grandpa is nearly seen, so Josh hides him under a poodle toilet roll cover that Loretta has knitted for Bob. When Grandpa sneezes, Mr Whoops thinks it's the poodle. Loretta puts it in the toilet and shuts the door, so Josh has to get him out.

Then Grandpa pretends to be a talking kookaburra, much to Mr Whoops's amazement. Meanwhile, Great Aunt Loretta is polishing the deck and falls into the water. Mr Whoops goes to help and falls in too. Josh finishes the cleaning and when Bob turns up he hears some very strange stories about his boat! Show less
