Watch very closely when Freddie throws the ball to knock down the milk bottles. After he knocks them down, he'll compliment himself. When he does that, look behind Freddie into the game booth. The milk bottles are standing up again!!!
I, too, noticed that when they throw the ball at the milk jugs, in the next scene they were all set back up, like magic! I attributed this strange occurance to being part of the mystery, and figured that the "paranormal being" that they are running from set the milk bottles back up.
