I know I said I wasn't going to bother listing my missing items for you, but what the hell. What follows is everything I need to complete my catalog (according to the Nintendo Power Player's Guide anyway) and my level of irritation with it: Minor, Major, Extreme, and Suicidal. If you want to help me out with some trading, toss me an email, but be warned, I don't cheat and don't use universal codes.
Furniture
Blue Tartan, Dump Model, Museum Model
These are just some items I missed last year. The tartan shirt is entirely tradeable; I just either forgot to buy it last summer or never saw it. The Dump Model and Museum Model are untradeable, but easy enough to get... although the Museum Model does ride on me getting Crazy Redd's damn Basic Painting first.
Gyroids
Mini Gargloid, Mini Echoid, Poltergoid, Mega Croakoid, Mini Strumboid, Mini Rustoid, Drilloid, Mini Oombloid, Mini Sputnoid, Sputnoid, Mini Quazoid, Tall Quazoid (untradeable)
Only minor irritation here. Gyroids may show up randomly after a rainstorm, but it rains fairly often and the buried gyroids never go anywhere if you forget to dig them up. Given enough rainy days, collecting all the gyroids isn't too terrible.
Flower Models
Pansy Model 3, Tulip Model 1, Cosmos Model 1, Cosmos Model 2
Groundhog Day is coming up, so maybe I'll score one or two of these. If not, they're easily traded. Plus, Pansy 3 comes on the Resetti eCard.
Island Items
Surfboard, Diver Dan, Life Ring (untradeable)
These items just require a little work. One of these days I'll get around to sailing down to Dred Island for some dig sessions with the islander. Yeah, this is more random nonsense, but at least I'm in control of when and how often I can do it.
Post Office Items
Mailbox, Piggy Bank, Post Office Model (untradeable)
These items come with banking tons of bells in the bank. A Valued Customer reward, I guess. If I can manage to hit it big in the turnip market, this is easy stuff. But that's much easier said than done.
Wendell Wallpaper
Mortar Wall, Ancient Wall, Sandlot Wall, Tree-Lined Wall (untradeable)
Stupid fat Wendell. It seems like he only shows up every three months and when he does, you get a random wallpaper that you already have. Asinine.
Snowman Series
Snowman Wardrobe (untradeable)
There are twelve possible Snowman items. I need one of them. It's a pain in the ass to make a proper snowman, and the reward is a random delivery of one of those items. So far this winter, I've made seven snowmen... and not only have they all NOT been Wardrobes, but half of them have been duplicates. Bite me, you stinking self-absorbed snowdink.
Camper Items
Propane Stove, Bonfire (untradeable)
The summer tent minigames are terrible. They're not fun, rely almost entirely on luck, and pay out with absurdly awful items. But occasionally you get a rare Camper item, of which I am missing two.
Gracie Shirts
Strawberry Shirt, Grape Shirt, Fiendish Shirt, Shirt Circuit, Pulse Shirt, Orange Pinstripe, Crossing Shirt, Giraffe Print (untradeable)
Piss me off. Another random item seller who distributes random crap randomly. And, bonus, you get thumb cramps from her obnoxious A button game.
Station Models
Station Model 1, Station Model 4, Station Model 7, Station Model 11, Station Model 12
Yeah, these are tradeable, but who the hell is going to offer them up? You only get one of fifteen per town, so finding the other fourteen means either trading for them... or making new towns and hoping against hope that they'll get the models you need. Nintendo was nice enough to put most of them as prizes on the eCard games, but not all of them.
Redd Items
Lawn Mower, Red Corner, Well, Basic Painting
The ultimate in crappy random distribution. Redd shows up never, and when he does, he only sells three items. And not all of them are even exclusive to Redd, most can be bought from Nook for less. So you never see the guy, he barely sells anything you want, yet he has a needed piece of every furniture series. This shithead is keeping me from completing my super-awesome Wild West room. Assclown.
NES Games
Punch-Out, Legend of Zelda, Super Mario Bros. (untradeable)
Who would have guessed that almost a year and a half after the game's US release, Nintendo would still have kept these NES games secret? Clu Clu Crap Land we get, but Punch-Out remains hidden. The Player's Guide only lists Punch-Out as necessary for catalog completion, but we all know the other two are in there too. Maybe someday they'll release the codes for these games, but even the most ardent of Nintendo fans has lost all hope by now.
So there you have it. 52 items, most of which are completely untradeable and frustratingly random. I sort of doubt that catalog completion was intended as the goal of the game, given how hard it is to do... without cheating. Maybe if you lived in a commune with twenty people playing Animal Crossing, you could work together to get one person to finish their catalog. Not that that's a bad idea, a building full of Nintendo gamers, just totally nuts.
