Football kids (
: jalkapallopojat) are the two kids playing 1v1 football on the sportsfield near the school in Peräjärvi. They play here everyday from 10:00 to 22:00. Yellow t-shirt kid's goal is at southern end of the pitch closer to the lake, white t-shirt kid's goal is at the opposite end. When one of them scores a goal, he celebrates it by silently raising his hands up. Yellow t-shirt kid is noticeably faster than the other kid. Therefore, he scores more often.
Playing football in the lake
Both kids' running speed is higher than the player's so you can't outrun them. Also it's not possible to knock them out or run them over. Instead of most other invulnerable NPCs that act as non-solid objects without collisions, the kids are actually solid objects that can push you and other solid objects in the game while running. This means that they can damage your Satsuma if you park it on the sportsfield, and you can die if you try to run them over with a car. The kids also do not interact with water in any way, meaning, if the ball gets kicked into the lake, they simply won't mind and continue kicking the ball.
The kid with the white shirt bears a strong resemblance to Fleetari. He wears the same clothes as such and also has a similar face, implying that he is perhaps related to Leif.
