You have probably heard about the hidden mickeys that can be found in everywhere on Disney property. But there are some parts about the World of Disney that are kept out of the spotlight. On my last trip to Orlando I wanted to see the World of Disney from a new perspective, I wanted to see and do things that I had always passed over on previous trips. These are a few of the hidden secrets I looked up and found interesting.
Magic Kingdom:

While exploring Tom Sawyer's Island, look for a paint brush hidden in the bushes that Tom has left behind. Give the paint brush to a cast member nearby and you will receive a voucher for immediate access to your choice of Thunder Mountain or Splash Mountain.
Head to Main Street U.S.A. to the candy store. Inside you will find an old-fashioned phone on the wall. Pick up the receiver and you will hear an actual phone conversation.
Epcot:
Walk to the back of the UK in the world showcase to find a butterfly garden and a rose bush maze.

When leaving the Test Track ride, look for the crash test dummies, they may not be fake dummies after all!

At shops and carts throughout the park, your child can pick up a passport and have it stamped in each country of the world showcase, travel to every country and receive a prize.
Hollywood Studios:

Upon entering the building to Muppet Vision, lift up the mat at the door, find a key and bring it to the nearest cast member for a prize.
Walk the New York Streets on the Avenue of the Americas and hear gangsters plotting their next move.
There are two scenarios on the Great Movie Ride. One with gangsters and one with cowboys.
Animal Kingdom:
Head to Camp Minnie-Mickey and listen for the two talking bushes Herb and Flora.
While playing the the Dino-Land Boneyard look for the crates and lift their lids to hear animals growl.
Arrive at the park 15 min early to catch Rafiki welcoming the new day.
Look out for DeVine a performer dressed as foliage she blends in so watch out!

Looking for these added touches gives you a special addition to your trip, enjoy!
