Someone says they were celebrating a party, the birthday party of a tribe called Nosoccer, looking at the members the researchers suppose it was the fifth.
An extraordinary event happening just once in a year, like the summer solstice. In case the same tribe will be sighted again, you’ll immediately know. In the meantime, keep an eye on any skatepark or rideable structure you could meet on your way, nobody knows if you could meet them.
