Have you ever used pitfall seeds? I personally haven't. I see them for sale at Nook's Cranny, and I am curious what you have done with them, or what they are even used for?
Not as much as I did in NewLeaf. You can also fall in a hole without the item. Dig a hole in a way that you can still sit on something and then hop off into the hole. It was fun to just be silly with my friends.
When I started playing the game I had about 20-25 friends who wanted to play with me on my island, and I pranked them so much (pitfall seeds, standing in front of their chair, etc) that now I have 0 people who wanna come to my island.
So, if you want some advice, don't overly use them.
