Hitting people

what happens in little league if you plunk someone?

They explode.

Kidding. Unless the kid’s a wuss then nothing happens to them and they just take their base. The pitcher might get a warning or a small talk from the umpire to calm him down. Usually if its 2 or 3 hits in an inning (or sometimes game or sometimes something completely different depending on your league’s rules) the coach might be forced to take him out.
