There's so many quirks hidden at Disney I could go on and on.
- in the Haunted Mansion graveyard, there's a tombstone for Mr Toad, they put it there when they closed Mr. Toad's Wild Ride.
- there's a talking trashcan in a food court in Tomorrowland. Sometimes it freaks people out. One guy dropped his whole tray. (the Disney staff replaced his order, thankfully, lol) There;s also a pay phone in Tomorrowland that if you pick it up you'll hear something unexpected.
- the dog in Pirates of the Caribbean holding the keys was modeled after Walt Disney's actual dog.
- there's a secret umbrella in Hollywood Studios, if you pull it, it sprays you and plays "Singing in the Rain".
- in Club Cool in Epcot there are free samples of sodas from around the world. Some are delicious, some are horrible. I forget the name of the grossest one but it comes from Italy and tastes like motor oil. Trick your friends into trying it.
-When crossing the bridge into Liberty Square, you pass over seemingly ordinary rocks in the water. They were actually mined from where Washington crossed the Delaware.
- in Animal Kingdom, and African King actually sent his roof thatchers to go and make authentic roofs.
- the Twilight Zone Tower of Terror has actual artifacts from the show hidden everywhere. My fave are the reading glasses that broke in the episode "Time Enough at Last"
- There are thousands of "hidden mickeys" at Disney (the 3 circles that connect like mouse head/ears)-- hidden images made into the decorations and landscape, they're everywhere. No one even knows how many there are because the artists and designers work them in. You can have a fun competition with your family to see who finds the most hidden mickeys on the trip.
