A closer look at Mer-Rick and Mer-Morty designs.

I can’t decide if Rick should have a coat or not XP

 I based their design off of a great white shark and a pilot fish respectively

Great white shark cause they’re called the kings of the sea and the spikes, they way they naturally demand respect, and never still nature of them I feel fits rick

Pilot fish cause they tag around sharks for protection in return for helping the shark all the while being devoted to the one shark they bond with, fast enough to keep up with the shark, and said to be compasses that direct to land/home for sailors (I was thinking like a moral compass in this case), It suits Morty just fine.

Normal mermaid Morty awesome but I have a soft spot for pilot fish Morty too, ah choices XP.
