Gyroids! They're ugly, serve next to no purpose, and they will appear in your town the day after it rains, which in fall is pretty much every. single. day. They're like that one stupid newsletter that spams your mailbox that you can't seem to get rid of. Except, of course, you can eventually get rid of the spam. Gyroids don't care. They just keep coming. My town's junkyard must be full of them, as they make up at least 90% of my trash.
The balloon set, definitely, since it's so ugly and you get a ton of it. I just wish there was a chance to get more interesting items from the balloons... Apart from slingshots, obviously.
The cardboard set. I understand that Gracie needs exclusive items and such, but really? 80,000 bells for a stack of crads? Who would want that in their house? And who would pay that much to get all of the pieces? I'm not looking forward to the day when I need to collect them all for my catalog. Damn me, for being a completionist.
Of course, the lovely set is just plain hideous. But if I ever need to set up an escort character, it's nice to have things to put in her home, I guess.
And finally, the bug boxes. I do have actual experience taking care of exotic critters and to see them stuck in that horrible box forever... Why can't we just have them in pretty terrariums?
I really am not fond of the ranch and the green series :/
I also don't like the theremin cuz the noise scares the hell out of me... combined with that squeaky bird thingy (forgot its' name lol)
Gyroids.
A few years ago, my house was literally STUFFED with gyroids. I didn't even really like them, I just wanted to raise my HHA score. Even my mom told me they looked like ugly fire hydrants and j should get rid of them. One day I was just like "screw this" and sold all the gyroids and cleaned out my house. Screw HHA, I never liked the prizes anyway.
