Unbelievable is the second in a series of collections of short stories by Australian author Paul Jennings.

A boy finds out that his nasty neighbor, Monty, has a bin filled with toothpaste, even though he only has one tooth.

A boy who is a fan of horror films and isn't scared of anything leaves his sister at home alone for a night because she has stolen his rented scary movie.

However, he meets an old man who tells him a story of how he worked as a busker when he was younger with his only friend, a little dog named Tiny.

However, his grandfather is embroiled in a decades-long feud with another old man, as they are able to transfer illnesses to each other by blowing into magic gumleaves.
