where in the world do I find these treasure boxes? If they are the ones that float in the sea, mine do not smoke, steam flame or bubble.
ok these are the balloon boxes that we are talking about. Pay attention, when you first pick up your box prize, as soon as you collect, keep your eyes on it, because very fast, the boxes will come back up for you to choose a new time. Here is a pic i just took after accepting my prize. the 2nd box has bubbles, You can see, but the 3rd box had lightning and i tried to get a shot of it, but it was gone before i could, and the 4th box had bubbles.. here is the pic.
here is the lightning (again, it happens very fast after you pick up your prize, so pay attention, the lightening does disappear)
for that last attachment, its kinda of tiny, so click on each one. 
I always thought the lightning strike meant that we were to select that particular crate. I misunderstood the language regarding treasure box in lieu of balloon box. Now, as you explained, I will be more cognizant of what transpires on each box after I hit the ‘ready’ to open box. Your explanation was very helpful. Thank you ! Have a beautiful day.
let me know how it works for you.. you definately get better prizes.. if i dont have anything special pop up, i pick the shortest time..
Thank you ! Your photo was very helpful.
