I wante
d to replace Nibble's Pear Bed with Luna's Bed and noticed that "Luna's Bed" did not appear on the List of Items tab in the Villager Furniture Replacement Guide. I thought that was odd, since normally all new items are added (e.g. the Surichwi Tteok item was added under the "Food" category) and I thought that
of course Luna's Bed would be in the "Bed" category. Nope! It seems to be in the "None" category for some reason, since Nibbles replaced her Tennis Table for it:
For reference, I had mailed her 3 Luna's Beds at the same time (to increase the odds of her replacing old furniture instead of just placing it in her NnpcRoomMarkerFtrFloor2x1 slot) and not gifted her anything else after that point.
Wanted to post this here since I could not find any other images online of a villager with Luna's Bed in their home. But having used the Villager Furniture Replacement Guide for all of my villagers, I have learned that if an item you're looking for isn't on the list, then it has to be in "None".
I have also observed something with
villager clothing storage. It appears that you can
not replace old villager clothes by gifting them 24 (or more) of the same clothing. I obtained a gifted Dom from someone, and I observed that he had been given at least 9 shirts, 2 hats and had on display 1 glasses (which he still sometimes wore). I replaced his Log Stool with a Safe to check his wardrobe progress (didn't want a wardrobe to fill his RoomMarker spot, in case he replaced it again with clothes), and I can confirm that after giving him 35 red Sea Captain's Coats and 10 red Top Hats, his "storage" still hadn't seemed to push out all of the old clothes he was given. I got rid of most things – but 3 things I just couldn't get rid of. His wardrobe still had the 2 hats inside. Yes, just the hats. A pink Giant Ribbon, which I have never seen him wear; and a red Colorful Striped Knit Cap, which he wore really frequently. He also wore a brown wool sweater with a tiny flower print on the top left, which had never appeared in his wardrobe (but he still wore all the time); and since I can not find the name of it online, I assume it was probably a custom design from his old island. Which if that was the case, Isabelle did an absolutely rubbish job of making him not wear it, haha!
Another observation I made is, potentially, a villager might be able to "store" a piece of clothing without it appearing in their wardrobe; even if they are not wearing it currently nor displaying it in their home. I gave Audie 4 Adventure Dresses, 9 Farmer Overalls, 9 Alpinist Dresses and 3 Hibiscus Hairpins. The Adventure dress eventually stopped appearing in her wardrobe and it wasn't on display in her house, so I thought maybe I had pushed it out of her rotation. But no, I still saw her change into it multiple times after this. Also occasionally, I'll see clothes randomly "disappear" from wardrobes on some days and reappear a few days later. Another thing that happened is that Audie had just the 1 Hibiscus Hairpin appear in her wardrobe for ages, then suddenly, he decided to put one of them on display in her home. It has never since moved from display, but neither has the 1 in her wardrobe. So this shows she owns at least more than one.
Finally, I have gotten Willow to display 3 pink Heart Aprons and have another still appear in her wardrobe. She displayed one in her RoomMarker slot, another replaced her Pintuck-Pleated Dress, and lastly she displayed one on her wall (which I have never seen another villager do before unless they already had clothes there by default, like Tom). It has been ages, and since then the only one she keeps on display is the one that replaced her Pintuck-Pleated Dress. I have also seen Tom wear a Pirate-Treasure Robe while having replaced his default Jumper Work Suit (on wall) with one. Again it's been ages, and the Pirate-Treasure Robe has never left the wall since.
To keep track of everything, I have kept tallies of all the outfits and items I have ever given my villagers, as well as taken screenshots of their house interiors and wardrobes on different days. Maybe I'm a bit crazy, but I'm just so curious at how the whole "storage" thing works! If anyone wants to see these though, then I'm happy to try and compile them together in a post on here.
