Stitches was a random move-in for me. I loved him instantly! This was at the time when I didn't know that villagers could be worth more than others so there was no "Oooh, I'm going to like him because everyone else does!" business.
Even though it's hard, try going for Stitches. His adorable face and cuddly exterior is worth the millions of bells you have to pay for him. People hold giveaways often, so he's not too hard if you know how to write a convincing reason.
