Everyone in the WoF community knows what a Rainwing is and their amazing abilities. They can change their scale colors to match their emotions and sometimes they can make their scales match their environment to become invisible. They can also release a venom from their fangs that acts like an acid that burns through everything that it touches. And they can do more but we aren't focusing on that. Today we are focusing on their frills. 

This is what a Rainwing looks like:

And this is an example of how people draw Rainwings:

Take a look at the frill on the second one. It has four separating spikes and three fins. Now look at the official base. It has four separating spikes but four fins. Here's a closer look.

See? They have one that everyone just forgets about. Maybe people just find it easier to draw Rainwings without the fourth fin I honestly don't know.
