What should I do to move Sen's aurora?

Nothing can be done. Aurora appears as a setting in special weather or games. There is a random weather system in the animal friends' meeting. The game of gathering animal friends is a simulation game, which also simulates many things in daily life. The gathering of animal friends will also have seasonal changes, weather systems and so on.

In the animal forest friends' meeting, you can make a wish when there is a meteor shower, and collect star fragments, big star fragments and constellation fragments on the beach the next day after making a wish.
