Weeping Vines

Weeping vines are plant blocks found in the Nether.

Natural generation
Weeping vines generate naturally on huge crimson fungi in the crimson forest biome.

A huge fungus grown by bone meal on a crimson fungus also has weeping vines growing on it.

Growth
Each random tick, weeping vines have a 10% chance of growing one block downward. At default random tick speed, each plant grows approximately every 13653 ticks. Weeping vines stop growing once they reach the ground or when the block reaches an block state of 25, whichever is first.

Obtaining
Weeping vines can be mined instantly with any tool.

Usage
Weeping vines can be placed on, and grow from, the bottom of a block. The bottom-most vine block always has a block ID of and have an  block state with a starting value of, which increments every time the block grows. All blocks above the bottom-most vine have a block ID of and do not have an  block state. If the bottom-most vine block has an age below 25, it continues to grow given that there is free space below the vine. When the vine does grow, the bottom-most vine block, which has a block ID of and an  block state, turns into a  (with no block state) while a new  block with an incremented  is placed beneath it.

Weeping vines can be climbed by standing in them and holding the key. If there is a solid block behind the weeping vines, the key can also be used.

Loot
Weeping vines have a $1/3$ chance to drop a single weeping vine when broken. Up to two additional weeping vines may drop per level of Fortune, though the chances of any drop occuring are not increased.
