Booty digs up a strange brass key, and it leads Papa, Rosco, Ravyn, and Booty to a museum that shouldn't exist.

Inside, they discover a collection unlike anything they've ever seen: a trophy Booty never won, a machine that drops sandwiches, a boat floating in soup, hundreds of impossible doors, and exhibits that seem to make absolutely no sense.

But the strangest discovery is hidden beneath the museum.

There they find a secret room filled with impossible things—things that never happened.

Could some of them still happen someday?

Join Double O Papa and the gang for another hilarious mystery packed with strange discoveries, scientific surprises, and one very determined dog.

Double O Papa: The Museum of Things That Never Happened is a funny, imaginative mystery adventure for young readers who love animals, exploration, puzzles, and the unexpected.
