Original Description:
 
Pinkie - “Bestiary”?  
Sunset -yes it is… Princess Twilight gave it to me… she has information about all the creatures of Equestria including mermaids, there I learned that they have a very developed sense of smell  
Pinkie -ooohh  
Sunset - that’s why I started wearing the clothes we took to that cruise … I figured I could still smell like sea salt with so much water that it fell on her and, since mermaids inhabit the sea, that would make Dagi feel more comfortable with me from the start, pretty smart right? you can say it  
Pinkie ~~uhum… hey… what does “hermacolita” mean?  
Sunset -what?  
Pinkie -here … in the “anatomy” part it says that mermaids are “hermacolitas”… NO! I read it wrong… “hermaphro…”  
Sunset -ENOUGH READING FOR TODAY !!!  
Pinkie -what does that word mean?  
Sunset -a-ah FLUSH HAIR !! means fluffy hair! You already saw Adagio’s hair, right????  
Pinkie -fluffy hair ?? like mine?? so I’m a sister too…  
Sunset ~~ ENOUGH QUESTIONS!!!  
Pinkie -mmmmmm
