Every now and then The Hero runs across a big animal he would rather not disturb. It's a bear, or a tiger, or Cerberus. Correct procedure is to back away slowly, making placatory sounds such as 'Niiiice kitty... good kitty..." then run just before the pounce. Occaisionally the Kitty turns out to be an actual Nice Kitty..., and acts like a giant puppy.
