i think they only have the tail during the day so yah i'd have the one with the (literally) fishy minge, and fuck it's brains out at night. either that or find one with a fish head and cut and paste them together, then i'd have a big fish to eat and a mer-woman.
bottom half fish, if the top half is fish there isno arms, so how the fuck is she gonna clean her faff? so there for u might have a minge and a bum but they are gonna stink of fish n all...lose lose in my eyes.
Mermaids are quite creepy and my right hand have been a good companion so far in my life. A human sized fish on the other hand would make for a pretty nice dinner and as long I don't stumble across any pirates who'll chop my right hand of... I think I could make it to the next harbor and fix a dinner for two with that fish.
