- "This is Peppi Bow. She was the last person to see them. Padmé sent her here to safety."
- ―Gregar Typho
Shortly after the beginning of the Clone Wars, the Gungan's herd became skittish when near Naboo's eastern swamps, in much the same way they had during the Trade Federation's Invasion of Naboo eleven years prior. She finds her herd killed drinking from a river just outside of Naboo's capital of Theed. She learned from Naboo politicians Padmé Amidala and Jar Jar Binks that her animals were the victims of a Confederate biological weapon that had contaminated the river. Bow aided the two in locating the weapon's source, and after Amidala and Binks were captured by Confederate forces, she aided Jedi Padawan Ahsoka Tano in locating the politicians. Bow and Tano discovered that they were being held in a secret Trade Federation laboratory beneath the eastern swamps—the same laboratory where the bioweapon was developed. While Tano and Republic forces assaulted the lab, Bow waited in the swamp above to prevent any Confederate forces from escaping the battle. At the end of the raid, Doctor Nuvo Vindi, who was responsible for the bioweapon and the capture of Amidala and Binks, attempted to flee Republic forces, but was stopped by Peppi Bow after she tackled and incapacitated him.
