not really sure but it kind of looks like a stomella snail or a nubi of some sorts.

I hope it doesnt have orange spots/spikes on it. I thought I had a slug like that once then found out it was a type of nudibranch that ate zoanthids! It sucked big time. Finally caught it though.

cant remember if it had spikes. I looked up its name and saw exact pics. Its a sacoglossan slug
