Shakespeare Pranks

In our play, our main character is Puck, a very spirited fairy who likes to play tricks on others. So we want to include a scene where Puck is pranking! A couple ideas I've come up with include: 

-a basic transformation of an individual into an animal. Puck did this in A Midsummer Night's Dream.

-Puck transforming himself into another individual to impersonate them and confuse someone else. This can lead the person in the wrong direction and could be quite funny. He could meet some travelers that can become separated from one another as he is going on his mission for Oberon. 

-Or he could come across a village and decide to mess with some of the people living there. Perhaps moving objects or making them think that a ghost is there by making up voices. 

I also came across this blog post that had some funny ideas. I particularly liked the Twelfth Night idea. Absolutely hilarious. We could easily do something that has already occurred in another one of Shakespeare's plays, and that could further prove our play is of Shakespeare origin. They also had different degrees of pranks involved. I'm sure Puck wouldn't do something completely cruel like the prank discussed in Othello, but it leads me to wonder how far he would go. To what degree of harm would the prank be or would it be completely harmless?
