Stomatella or Something Stranger?

[QuiGonJay]

Any ideas for this small guy? Only seen him once (at night). Very small - about a cm. Doesn't seem to have any shell but two noticeable eye stalks/antennae.

Trying to sort out of its harm-less or ful.

Thanks!

I'm a sucker for stomatellas. They're really cute in a squishy way. Unfortunately I rarely see the ones I have!

when I had them they bred like rabbits.
