Aogaeru

Aogaeru (あおがえる, aogaeru, lit. "blue frog") (Also known in America as "Ethan") is a frog spirit and minor character in the Japanese animated film Spirited Away.

In the film,  he jumps into Chihiro's face while greeting Haku, causing her to fail at holding her breath while they cross the bridge leading to the Bathhouse. When he yells that there is a human, he is promptly suspended in mid-air by Haku's magic for a moment while he and Chihiro escape to the back of the bathhouse. He is released soon after and runs to report the breach.

Aogaeru is the first of three spirits to be devoured by No-Face, but is freed before the end of the movie as No-Face leaves the Bathhouse to follow Chihiro.

Personality
Aogaeru is shown to be greedy, just like most other Bathhouse workers, when he sneaks back into the bath room at night to try picking more gold left behind after the unnamed River Spirit incident that could possibly be stuck in the cracks of the floorboards. He is subsequently consumed by No-Face after being enticed to walk up to him with some fake gold.

After being freed, he appears more benevolent, as he cheered for Chihiro after she managed to get out of her contract.

Quotes

 * "Where you been?"
 * "It's gold."
 * "You can make gold?"
 * “Give me!”
 * "Gold?"
 * "Madam, you see, Zen was the one who saved us from No-Face."
 * "Master Haku?"

Trivia

 * No-Face's assumed Aogaeru's voice after consuming him.
 * Similarly, No-Face seems to absorb Aogaeru's greedy personality after consuming him. After No-Face regurgitates all of the people that he ate (including Aogaeru), he becomes calm and docile again. Further speculations about No-Face’s powerful adaptability and behavior are elaborated on in his article.
