Buddy's Lost World is a 1935 Warner Bros. Looney Tunes cartoon, directed by Jack King.
[3] The title is likely a reference to the 1925 silent film The Lost World, itself based upon the 1912 novel by Sir Arthur Conan Doyle.
The crowd stands on a dock, which is pulled apart as Buddy's motorboat, still tied to the structure, sails away, leaving the people floating in the water.
This process takes Bozo through a forest, dominated, as we find a Barapasaurus, whose discovery frightens the dog into a run.
Buddy calls after Bozo and is eaten by a gigantic, ravenous plant, whose digestive tract leaves him on a hillside, overlooking a society of cavemen, some hard at work, others busying themselves with croquet.
