Never had Pietro before NH, but now I love him! He's the perfect smug, imo. His over the top colorful design goes well with the 'full of himself' smug but ultimately sweet disposition. I also sort of like that he has the potential for 'creepiness' (in a fun way). He once told me that he loves his basement because no one can hear him scream there. Perfect dialog for Pietro!
I'm personally not a fan of Pietro but I don't really think he's all that creepy. He's just... kinda ugly imo. I used to dislike him much more, but ACNH let me loosen up a bit to him, after seeing him on people's Dream Addresses, and during island hunts.
i currently have pietro on my island and he’s wonderful! i didn’t like him at all during my new leaf days (never found him creepy, though) but he’s genuinely super cool imo and is really nice to have around! his interior’s a bit of an eyesore, though.
I didn’t like him at all at first because I really don’t like clowns and I don’t understand what their purpose of existing is for. I’ve started to appreciate him more though because so many people like him so now I just tolerate him.
