Aliasing pink_cheeks → cheek_spots
Link to alias

Reason:

This is more of a loose suggestion, but cheek_spots has more posts than pink_cheeks. Also, there's red_cheeks. All three of these tags contain pikachu and other characters with spotted cheeks. And all three of these tags also do not have wikis, so it's hard to tell which is "official".

Edit: I spoke too soon--red_cheeks does have a wiki.

There's also blue_cheeks (and probably other colors). Make of that what you will.

Alternatively, a tag colored_cheeks could be made and all the *_cheeks could imply it.

Thoughts?

EDIT: The tag alias pink_cheeks -> cheek_spots (forum #262348) has been rejected by @NotMeNotYou.
