Beta

&nbsp Something beta is something that is changed or not in the final version of the game. This information is usually given out before the game's release, or data left in the game that is not seen through normal gameplay. There are not as many beta elements in the Animal Crossing series as there are in others, though.

Examples in other games.
Many games have beta elements. One example is in the game New Super Mario Bros. Wii. For those who haven't played it, there's an item called the propeller shroom. While it's an orange mushroom with yellow spots and a propeller sticking out of it now, originally, it was a red "P" with a propeller on top of it when shown at an E3 presentation.

In the Animal Crossing series.
There are few beta elements in the series. One that could be considered beta is the item "DUMMY" in the Animal Crossing (Gamecube). It is not really used in the final.
