The group stayed for a two days, they probably could have stayed longer but Miku insisted on leaving a bit early so they wouldn’t be escaping from the Fire Nation at the last possible moment. She said it was so they could put some distance between them and the Fire Nation that was chasing them.

She had stuff like pots and pans for cooking, dishes and utensils for eating, a tent, sleeping bags, a water purification system, various preserved foods, a map, and a few other necessities.
