My dh and I were at WDW June 1-6 2007 and the first night we were there, it was the beginning of tropical storm Barry, it was pouring for the first two days and there were the tiniest little frogs I have ever seen, I took a picture with my cell phone but I don't know how to get it on to here, they were so cute and so little, I tried to catch one and take it home to show my kids but I couldn't find them once it stopped raining.
We have always seen little rabbits in Epcot, over by Mission Space, in the little gardens they have in the pathways, and in Magic Kingdom. Once we were leaving Mk for the day and walking up the path to where you load the resort buses and a squirrel shot out from the grassy area and ran across my foot, it like to have scared the crap out of me. Not to mention having our plates dive bombed by birds in Frontierland.
