A workman finds a singing frog in the cornerstone of an old building being demolished. But when he tries to cash in on his discovery, he finds the frog will sing only for him, and just croak for the talent agent and the audience in the theater he's spent his life savings on.
Unfortunately the movie One Froggy Evening is not yet available on HBO Max.
