Kongamato

After defeating the cave serpent, King Kong followed Ann Darrow onto the cliff outside his lair, where she was attacked by a Kongamato, which tried to carry her away. Kong attacked the pterosaur, freeing Ann. Jack Driscoll reached the cliff and rescued Ann while Kong battled the giant pterosaur. After killing the Kongamato, Kong tried to pull Ann and Jack back up by the vine they were climbing down, only for them to jump into the river below and escape unharmed.
