Also, it is definitely the same Nuckelavee that killed his parents. He found one of his father's arrows in its cave. That's what Ren picking up an arrow was supposed to signify to us, without just telling us to our faces like we're 4-year-olds.

That, and the crew have told us that the Nuckelavee was actually a fusion between two different Grimm - the horse-like one and what they call an Imp Grimm. Sooo, unless someone created another fusion, it seems that the Nuckelavee was actually a unique Grimm with no others in existence.
