Watch Who Killed Cock Robin? (Short 1935) online — it may be available on legal streaming platforms such as YouTube, Netflix, Prime Video, Hulu, Disney+, and others.

Robin is crooning to a Mae West-like Jenny Wren when he is shot with an arrow. A court is convened; the judge, an owl, keeps singing the title. A variety of birds are brought to the witness stand, but nobody knows a thing.
