"……Fish, Dolphin, Duck, Cat, Anchovy, Appa-yah, Yesung ♥ (…omitted…) who [I] only become even closer to as the years go by. Thanks to you, I always feel secure.”

 "...handsome Minho, song boyfriend Jonghyun, EXO Suho, Sehun, and more. I'm always strong thanks to you guys.”

And this is how fans interpreted the pet names:

FISH=Donghae

DOLPHIN=Xiah Junsu

DUCK=Leeteuk

CAT=Heechul

ANCHOVY=Eunhyuk

APPA-YAH=Kangin

And I strongly agree... It's nice to know that if it's really Junsu the dolphin she's referring to on her thanks to that they still keep on contact with each other...
