Stitches definitely! Although, Coco is growing on me these days. She's not someone I would go out of my way to adopt but if she ended up in my town. I'll keep her for a bit.
I love Stitches, Coco, Lucky, and Tangy! People seem to hate Coco and that makes me sad because it's not really her fault she was born from a rabbit and a gyroid falling in love.
I think Stitches and Peaches are companion villagers.They both look like stuffed animals and have similar house interiors.Peaches looks like a stick horse.
