3 on 3 with Bumpers

This game is 3 on 3, but really turns into a 3 on 2 down low drill.  In each zone there are two teams of three players. On each team there is a designated "bumper".  The Bumper can come to life when one of their teamates passes them the puck. 

To start the drill, the coach throws a puck deep into the zone.  The players goal is to score, however, their Bumper must be activated in order to score.  So when a player gets control of the puck, their first action should be to get the puck to their bumper.  The bumpers cannot move until they receive a pass from their teamate.  Once the bumper receives a pass it is then a 3 on 2 down low.  The bumper is de-activated when the other team gains control of the puck.
