My Epcot snake story...
My family and I were sitting cross-legged on the pavement scooched up to the metal railing in Epcot waiting for Illuminations to start (near the bridge linking France to the UK). We were making a few strawberry crepes disappear, when a lady standing behind me gently tapped my shoulder and said "I don't want to alarm you, but there's a snake heading your way." I looked to my right and saw a 3 foot snake (don't know what kind, it was dark) slithering towards me. I slowly backed a bit away from the railing and made my kids do the same and the fellow just went along, minding his own business. We were just getting settled back at the railing after he passed when we heard this ungodly shriek. Some man completely freaked when he saw the snake, but instead of just moving away, he grabbed the poor thing and threw it up in the air, where it landed in the water. There were a couple seconds of silence, then people started yelling at him for throwing the snake in case it wasn't a water snake and couldn't swim! That was one weird night.
I did have a duck come into my villa when Disney Institute was still in its heyday. She just pecked on the sliding glass door, and when I opened it, strolled in to the kitchen, took some corn flakes I'd dropped on the floor, then wandered on out again. My family always jokes about the Disney ducks and Disney birds and Disney squirrels that seem, oh, magical somehow ;-)
