Wierd snail? I think...

[Jelloshots1613]

I recently found this snail like creature in my tank, but I haven't introduced anything new to the tank in months which makes me think it was really small when it was introduced accidentally. I think it could have been a snail baby, but it doesn't look like any of the snails I've intentionally put into my tank. Any clue what this might be?
