Grass carried

 grass_carried  was a block which was used for storing the item model for grass blocks.

Obtaining
grass_carried is only known to be obtainable through the use of inventory editors and other external tools.

Breaking
grass_carried can seemingly be broken instantly, regardless of held items. However, they do not seem to drop themselves.

Appearance
grass_carried obviously highly resembles the actual grass block. However, there are two key differences between it and normal grass blocks:
 * The top texture is a noticeably different color, and in fact matches the side texture much more than normal grass blocks.
 * This is due to this block using a pre-tinted texture, whereas the normal grass block uses a grayscale texture with a constant tint.
 * While grass blocks use the dirt texture on the bottom, grass_carried uses the side texture on the bottom: Grass Block (item under) BE3.png

Functional differences from grass blocks
Despite very closely resembling the grass block visually, grass_carried has notable functional differences from normal grass blocks:
 * It can be broken instantly.
 * It does not drop anything at all when broken.
 * As is the case with the majority items at the time which were not obtainable legitimately, it had no icon in the inventory, and would show a red background in many cases.
 * It cannot be turned into farmland.
 * Blocks which require a dirt-like block below them to exist, such as flowers and sugar cane, cannot be placed on it.

It is also said that placing a block on top of grass_carried will cause it to eventually try to revert to dirt like normal grass blocks do, eventually causing a game crash.

Issues
grass_carried is a removed block and as such issues relating to it cannot be fixed.
