[Anthropomorphic cat mermaid (mercat) swims above a glowing underwater city, with 3 smaller concept variant panels below.]
This whimsical fantasy digital concept art set features a mythical mercat, an anthropomorphic cat mermaid, exploring a sunlit deep blue underwater world with a futuristic domed undersea city in the background. The large top panel shows the friendly tabby mercat with flowing turquoise hair, jeweled accessories, and an iridescent blue scaled tail, surrounded by glowing purple jellyfish, a passing humpback whale, tropical fish, and vibrant multicolored coral reefs. Three smaller lower panels display alternate poses and design iterations of the same mercat character, all rendered in a luminous, highly detailed magical fantasy art style.

Haha, I couldn't resist it, especially since there are more than one meaning for catfish, lol.

Bobbie

Wonderful. Now she's a catfish if ever there was one, lol.

cocoayoc

new take on catfish

CaylaCatz

yeah, I didn't know if you knew that. It happens in SL a lot. Apparently when they introduced voice to SL ages ago, suddenly a lot of people were outed

CaylaCatz

good thing they have lots of babies or they would have gone extinct long ago

legion

Very cool! Well, they probably would have eaten all the anchovies and sardines, hahaha.

legion

Yeah, yeah... that's what they said—nothing bad would happen just because of one more...

CaylaCatz

yeah, a lot of guys suddenly found out half their nubile slavegirls weren't women

CaylaCatz

Thank you! Yeah, she loves being one.
