An Iceberg Budegassa (氷山ブデガッサ, Hyozan Budegassa) is a cold-blooded fish with cerulean blue skin. Their sub-zero skin was the result of ocean temperatures tanking to 2 degrees. You would have to oven their fins for 2 hours in order to properly chew on them.
Due to my lack of skills in drawing, i can't exactly show you what it would look like.
