Slug what kind

[flowflezy]

It’s dead but bright red and crazy looking was in some rock on wall hammer any idea?

 

[Tahoe61]

Does it move?

Is it Red Valonia or a red Stomatella?

Did I killed it loving it out

It does look very much like a Stomatella snail to me. Great little herbivores to have around - and not real keen on being pulled off of wherever they are crawling. They'll often drop their tail section if they're forcibly removed.
