Talking to Mayor Lewis ends the festival. When the festival ends, you will be returned home at 12:00AM.
Besides the migration cutscene, this festival does not have a booth and it provides no other benefits to the player.
It is possible to sleep through the festival completely.
Before the festival starts, if you use a Beach Totem you will consume the totem, and the text 'Today's festival is being set up...' will be displayed.
