Models and objects not used in the game, simply put.

Note: further hacking(for the majority of the screenshots) were done to remove any unneccessary scenery before taking the screenshots, thus only showing the model/object of focus and interest.

Corn Bag:
Corn Bag
An Bag of Corn. Where this would of been used i have no idea, though it may have been somewhere in the barn in Barn Boys at one point. Originally thought to be the Pikachu model at one point in earlier versions, this seems to not be the case now that the ECTS version is out there. However, if Rare intended to use it later on or not remains unknown.

Badly Textured Moneybag:
Badly Textured Moneybag
Looks like an early version of the final moneybag. The only difference is the texture it uses, ie it looks like it’s been thrown into a trash can and getting itself dirty.

Pikachu Tail:
Pikachu Tail
The tail of an very popular mouse pokémon. This tail was, according to an post on Chris Seavor’s twitter page, used for an cutscene they were forced to cut at nintendo’s request. It was originally believed that the tail would be placed on the back of the Pikachu model, and that several animations depicting either Conker or one of Don Weasos henchmen sitting down and petting it was intended for the scene, but with the discovery of the ECTS Prototype version these things have been proven false, as this tail was all that was meant to be seen, and the Don would try to beat it to death(according to the punch sounds during the video)

All of the first three beta models can be viewed ingame by replacing Conker’s 2nd image(which also is the one used for Conker in multiplayer). All codes below are for Player 1. Remember to not yet turn on the code while in an area. Leave it first, and while the new area is still loading, turn one of them on. When the screen fades in again, you’ll be the character specified by the code. They´re only for PAL right now.

Non Character Models:
Yep, even this set of object models has unused goodies hidden within. Most of them are accessed with the below code:

Pull out/Put Away Home-run Bat(PAL)

810CC778 0000
800CC6F5 0000

D0042DA4 0002
810CC774 010F
D0042DA4 0002
800CC6F3 00C6
Press d-pad Right to pull it out, d-pad Left to put it away.

The code is to be used with the below codes for each model. Some of these models have animations as well, but I'm too lazy to write about them. The majority of the codes below replaces the Home-run bat model. Most of these are only for PAL atm. I will port them to NTSC later.

SHC Laptop:
SHC Laptop
An laptop presumably intended for one of the SHC squirrels. Can be seen with the below code (note; it is upside down when it appears in Conker's hand. In the above shot I had to rotate Conker so it appeared correctly):

8109D880 9909
8109D882 000F
8009D886 000F

Intended for an Army squirrel. Was first seen in a promotional trailer, but by the final version had disappeared, and seems to have been disabled. By using any of the below codes you can now see the walkie-talkie again like in the trailer video.

80086EF8 0002
8109D170 9612
8009D173 0001
8009D176 0000
Note: the code replaces the also likewise unused Bug-catching-net object below. There’s a noticable side effect to this, particularly in the “Assault”, where the other squirrel soldiers are affected as well.

Screenshots showing the walkie-talkie being used in the final game via the above codes:
Once gone, now backOnce gone, now back 2
If you want to see it in areas outside of the Assault scene, use this code together with the ''Pull out/Put Away Home-run Bat'' code:

8109D880 9609
8109D882 0001
8009D886 0000

Bug Catching Net:
Bug Catching Net
No idea where this would have been used, though it seems to come from early on in development when the game was being changed, so this is possibly not leftover from Twelve Tales. Further rumors has it that it was to be used by Don Weaso for catching the Pokémon with, and it seems very likely possible. But there's no real proof about this yet, not that I know of at the moment. Can be viewed ingame with the code below:

8109D880 8B09
8109D882 0002
8009D886 000E

An table candle stick. By the looks of it, it seems to have been in Count Batula’s mansion once, on the dining table where Conker have himself a feast.

8109D882 0001
8009D886 0000

Remote Controller:
Remote Controller
No idea where this could have been used. Perhaps in one of the parts of the It's War chapter? Can be seen with this code:

8109D880 8A09
8109D882 0002
8009D886 000E



Opened Chest Part of SHC Soldier:
SHC Solider Chest
Seems like the usage about this one has finally been confirmed. It was once used on a SHC soldier in a cutscene that was cut from the final game very late in development, where he is being experimented on in the Tediz lab, still fully alive. This object is still present in the final game, though unused obviously, and can be seen ingame with the below code:

8109D880 7509
8109D882 0001
8009D886 0000

White Thing:
White Thing
What this one is, and where it is/was to be used I don't know. The code below let's you see it ingame:

8109D880 A109
8109D882 0002
8009D886 000E
This one looks like it is being used in game, but it is not. Instead, a copy of the model is stored with the Character Models that is used on Conker when he transforms into a anvil. I can't yet confirm this for sure, and it could use some further investigation to confirm whether it's used or not. Use the code below to see it:

8109D880 8609
8109D882 0002
8009D886 000E

Twelve Tales Crate:
Unused Crate
An background object originally featured in the now gone Twelve Tales game. Note that the texture of it has changed since the first promo video of Conker's Quest.
