Some snakes just look really weird, unique for their morph. Even some normals can look so intense or unique, that they seem to be morphs of some sort. I once had a ghost morph that looked so strange, I swear he was more than a ghost. I could not find a single photo online of a ghost (hypo) that looked quite like his coloring. Yet, he was just a ghost, just a very unique one.

You have a unique lesser! It may or may not be het for green ghost, but it really doesn't matter.
