5. They used Jell-O to color the horses.
Did you ever wonder how they gave the horses those vibrant colors when venturing round Emerald City?
The horses were purple from Jell-O!
Well, wonder no more because the trick behind these purple horses comes from a simple tub of Jell-O.They had to get filming done fast because the horses wanted to lick themselves clean during the filming. I think I would have licked myself clean too if you covered me in Jell-O!
