You may recognize this wolf howl from a
 certain Jim Henson production.

An upbeat and cheerful woodwind
ensemble.

A very fast, digital, and somewhat erratic 
xylophone melody.

A quick and high-pitched xylophone 
melody.

A fast, low to high note, and metallic xylophone roll.

A somewhat, tarzan-esque, yahoo sound
(one of my personal favorite sound
  effects, in fact).
