Clever name fore a slime being?

I'm writing a story, and I need some clever ideas for an evil slime beings name. Nothing like 'slimy ooze' please, I'm trying to find one that doesn't sound so generic.

I made a fanart of a couple I like. This is the first drawing:

This is the second after a little while after the first:

As a writer, how would you describe this face?
I'm trying to describe him for a short story, he's 18 years old.

I understand that this might not be the best place to ask, but I'm trying everywhere.
