I am glad you kept her. I have been searching high and low for her but everytime someone has offered her to me none of my villagers will ping to move. I am even willing to trade Diana for Coco.
Coco's amazing!
I also have her in my village and I love her. <3
But then Skye is as equally amazing, so I understand why you are struggling to make the decision, they're both so cute!
I'm biased to Coco because I've had her in the past and in my WW town years ago and she was always my favourite.
