The Elite item-matching and elite scavenger hunt are ugh. But I don't even really like the basic item matching and scavenger hunt tours to begin with. I just wanna walk around and catch bugs and stuff.
I actually find the elite scavenger hunt tour fun and easy. Memorizing the plant names can be annoying at times, but overall I like it.
Hide and Seek is nearly impossible on the island, and I really don't know why. The closest I've ever come to finishing it was when I found three of the hiding villagers, but that's it.
