This is a rendering glitch in the way Minecraft PE handles invalid items.
I think any 4-digit ID would work.
To make specific items:
Top-left corner (leather helmet) = damage 0, the one to the right of that is 1. The pattern applies all the way to the bottom-right corner, 255.
For example, minecart is (8 * 16) + 7 = 135 damage, because its icon is 9 rows down, and 8 columns to the right.
This is a glitch, and those items crash PE, so they will not be included in PocketInvEditor.
Finally, there is no code powering those items - this basically just lets you select any icon for an item. They do not mean that those features are coming.
Ummm I tried this with plug pe by doing .g 1937:108 And it just doesn't work. .g means give and the four digit number is the1937 and the :108 is the damage value which is the enderpearl. WHYYY
