It was a combined activity involving a water balloon fight. She was protecting it with her life since they aren't supposed to get wet and cost $6K (yes, there is an Office scene involving the price of the ruined CPR dummy...).
One of the YM also has his robot baby tonight and was seen running away from water balloons, holding the robot by an ankle. He is screwed because it docks you points if the sensors think you were shaking the baby.
