Rubber Ducky You're The One

You make puddles so much fun

So I'm walking along the paved path that run through the middle of the area surrounding the Green Stage and can see a giant puddle up ahead with what looks like some trash floating in it. When I got closer I saw that it was three yellow rubber ducks! The level of creativity exhibited by my fellow Fujirockers never ceases to amaze me.

I wonder where whoever did this got the ducks from?
