Answer: Sounds like a critter is infatuated with your Elephant's Ear plant! Do you have Mountain Beaver in your neighborhood? I have had a similar experience in the past and it turned out that a Mountain Beaver was chewing the leaves off and dragging them to his/her den. Sometimes they drop them along the way and never quite realize it. The next morning we found a trail of leaves leading up to his/her den. Very odd!
You might try just throwing some bird netting over the plant for a few weeks. This should discourage whatever is gnawing on your plant. Hope so!
