Aogaeru

Aogaeru (あおがえる, aogaeru) is a frog spirit and minor character in the Japanese animated film Spirited Away. He is the second spirit to notice "a human" (or Chihiro/Sen) on the bridge when she breathes & is frozen by Haku/Nigihayami Kohaku Nushi for a moment. He is the first spirit to be devoured and empathetically adapted by No-Face but is freed before the climax of the movie.

Trivia

 * No-Face's voice was changed after it ate Aogaeru before it spit him out.
