A norwal is a undersea animal. It is very rare and quite hard to find.
That joke is inappropriate.

The narwhal's horn, which is actually an elongated tooth, can grow to be quite long, typically measuring between 6 to 10 feet (1.8 to 3 meters). In some cases, exceptional specimens may have horns that exceed 10 feet. This unique feature is primarily found in male narwhals and is often used in social interactions and displays.
