Bob's Australian Uncle Vincent has come to visit Sunnysands and is staying on the boat. He meets Great Aunt Loretta and invites her and Elsie to have tea with him aboard the Boomerang.

Loretta has taken a real fancy to Uncle Vincent and declares he is her dream date. Grandpa decides he'd better go along too, so on goes the Shrinking Cap. Uncle Vincent and Great Aunt Loretta are getting on like a house on fire, but Bob is alarmed when he hears that Vincent is planning to set up permanent residence on the boat.

In the hope that Vincent will want to go back, Grandpa tries to remind him of how wonderful Australia is - but his plans fail. That is, until he pretends to be a baby crocodile - Vincent is scared of crocs and declares he can't stay in Sunnysands a moment longer. Great Aunt Loretta discovers he isn't her dream date after all. Show less
