This subspecies is called "Reef Shishoodle" and is considered uncommon. They grow real, working fish tails and are usually very bright and colorful. Their fur is very shiny, almost glittery, and their eyes have two colors in them, instead of just one!
The rare Calamari Shish will always have some type of calamari/squid/octopus for a tail and can commune with the supernatural.
Say hello to the Junker Shishoodle! These kiddos are based on unhealthy foods like candy, burgers, cake, ect., and their mouth, inner ears, pawpads, and "heart" leak sugary and/or greasy ooze. Junker Shishoodles have a very different metabolism than other shishoodles, and are forced to eat fatty treats on a regular basis to keep their energy up.
