i add a merman from the gallery, sent my sim over to say hi. and lets swim together. i wanted to see the tail in action. he swam like a regular sim. and yes he was a merman. i turned off my mods, i only use mcc. but i thought hey you never know. and still no tail! what's up!? :(

They're in disguise. You have to add a mermaid into your household or become one yourself or perhaps become really really really good friends with them before you find out they're mermaids
