When Aang entered Forgetful Valley during Team Avatar's search for Ursa, his face twisted into a strange expression in a similar manner to what had happened when they first encountered the wolf spirit. Sokka pointed out that the face Aang was making was similar to the markings on a nearby flutter bat, and Aang attempted to follow it. The flutter bat, however, flew off, and Aang was forced to create an air scooter to keep up. The bat eventually reached one of the four pools in the forest, and Aang ceased his pursuit, believing that the flutter bat had been leading him to the pool. The flutter bat subsequently flew off.
