I think you're mixing them up with "beaver tails" -- a Canadian fried dough treat that they used to have in Epcot.
Elephant Ears is the "English" name for palmiers. They are basically cookies that have been made from puff pastry, sprinkled with plain sugar, and rolled into a stick and then both ends are curled in ... resulting in the look of ears or palm leaves. I couldn't find a pick here on the boards, but you can see them on this recipe:
Disney anglifies a lot of the treats. Napoleons are called "Mille-Feuilles" here in Canada. I don't find many of the treats in Epcot to be all that authentic.
