Camping

Camping is a common pastime shared by many in all regions.

Nanu's Revenge
In chapter 13, Naomi mentions stumbling across a poacher's camp. She had to put down many of the Pokémon that were suffering, something she regrets and haunts her. In the same chapter, she asks if Nanu had ever been camping, and he says yes, when he was a child. She also mentions that her mother, father and uncle would go camping three or four times a year on Treasure Island. It is unknown whether or not her cousin would join her, but it's possible he wasn't interested. They came across an area where they would often go camping and Nanu and Naomi settled down in the area.

In chapter 14, Nanu offers to watch the campsite, as he was used to staying up late. He counted the stars until dawn came and Naomi let him sleep a little while before making breakfast for them.
