As told by the storyteller:

Uly tells Mia that the yellow sickness strips animals of their reason and sends them on a violent rampage until they succumb to death. Mia calls him a liar. He apologizes but can tell that Mia is angry. At the edge of a swamp, Uly struggles to navigate the unfamiliar footing, pleading to take another route. He confesses that he is terrified of the Golgathursh, a lurking creature of the swamp that his sisters told him is made entirely of mouths. Mia rejects the idea that this animal exists and presses Uly to muster his courage. He reminds Mia that her siblings died of the yellow sickness, which she also insists on denying. Hurt and angry, Mia scampers off by herself. Uly calls out and apologizes, hoping that Mia will return. He is left stranded on a small patch of land. Around him, tall white birds begin to cry out, and Uly watches as the water suddenly surges and a giant mouth snaps a bird between its jaws and drags her into the water.

Mia reappears, explaining that she doesn’t leave foxes. The jaws appear again and eat another bird.
