Inspired by one of idontsleep posts
Nayeon - Squirtle, duh because she compared herself to it in Sixteen and they have the same cute little "teeth" (or lips that look like bunny teeth on Squirtle)
Jeongyeon - Bulbasaur because the little bulb matches her classic bowl cut 
Momo - Psyduck because it's her favorite pokemon and she has a sweet personality like a psyduck
Sana - Sana could go with a lot of pokemon but for her I chose Dedenne because she has a personality like it and she is often compared to a hamster
Jihyo - Jigglypuff because of her cute and fluffy cheeks
Mina - Piplup because Piplup is based off a penguin and Mina is often called Penguin (I couldn't find a picture of Mina with a Piplup but here's an edit not made by me)
Dahyun - Charmander because she always has this cute and spontaneous personality that reminds me a lot of a Charmander
Chaeyoung - Pikachu because she looks like a pikachu! She's always so cute and she always looks young and can also be sweet pikachu or electric pikachu with her looks
Tzuyu - Eevee because she has pointy ears like it and can be literally any Eevee evolution out there.
