Pietro is, sadly, a rare villager. I was very lucky when he arrived, unprompted, in my New Leaf village. But never fear! You can always purchase his amiibo to summon him to your New Horizons island. Though the cost of his card skyrocketed in the early days of New Horizons, you can now purchase his amiibo for the relatively low price of $24.95 on Amazon. Hey, it’s better than the $40 it used to be!
