The Last Airbender, Moon Spirit koi fish

original movie prop

This Moon Spirit koi fish is made out of rubber, and is 23 x 6 inches. It was the only one made for production. It was used to place in the bag then Zhao killed it. There are still fibers from the bag on the fish.

About the fish:

The Moon Spirit's color remained white and a spot on its back glows every few seconds. Placing the Moon Spirit inside the bag did not affect the waterbenders' ability to bend; they only lost power once it was stabbed by Zhao. The moon then turned red, though did not disappear altogether. Aang and Yue were affected by the disturbance Zhao was causing to the spiritual world. When the Moon Spirit was killed, Yue fainted, and Aang felt a sharp pain that shot through his head.

Yue was given life by the Moon Spirit when she was a stillborn baby, which caused her hair to turn white. She returned her life back to the Moon Spirit by lying beside it in the oasis pool. Blue-white energy leapt from Yue and moved into Tui. In the process, Yue's hair turned from white to black. Yue's body did not disappear and become transformed into the Moon Spirit. Instead, it was left behind as a lifeless vessel, mourned by Sokka.
