Can anyone ID for me, please?

Can anyone ID this critter for me, please? It appears like a snail from underneath (it’s attached to front glass) but on its top, there’s no shell per se. It’s soft looking all over. Been in the same general spot for about 24 hours or so. With flow off, I noticed it had “hairs” that you can see in the pic.

Thank you. It was hard to get a great pic, because my phone camera kept wanting to switch lenses on me when I tried to get a focus.
