I believe that you are asking about the actual flash that appears around Sam's body then he leaps, right? Or are you talking about the smiley face that's leaping?
If you are talking about the actual body flash -- that might be something that Brian might know about. I remember somewhere where he had a picture of himself leaping out. I've always wondered how he did it... and it might be a secret that he's keeping to himself. Who knows? But you can always ask!
IF you are talking about the smiley face that leaps, you'll need to do as Ross said up above.
Sorry that I couldn't help you more.
