Maybe we should give it a name? Maybe like Otruso, since it's an otter but very beautiful and flamboyant. If yu're trying to describe it in your story you should say like,
The green bodied animal with the purple patterned wings approached.
I'm not exactly sure if you're using images in your story, but explaining it a little then letting the animal have a flare moment it will catch your readers attention greatly. And tell whomever drew this that I would totally get this inked on me for apart of my sleeve ~(:
I hope this helped!
