Lily Pad

The Lily Pad is a block found growing on water in swamp biomes. Lily pads are walkable and breaking the lily pad will place it in the Player's inventory, but apart from this, little else is known about them.

Placement
Lily Pads may only be placed on top of a spring or a flowing spring. When placed, Lily Pads face a random direction and this will not be affected by the position or direction of the player. Lily Pads occupy the block above water and are not part of the water block itself. There is also a but with lily pads during placement. Sometimes when a lily pad is placed, it appears to duplicate to an adjacent block. However, when the duplicated lily pad is destroyed it does not drop anything.

Potential Uses
Lily Pads' primary use is for making paths over water without having to build bridges or use full blocks. This is very helpful for crossing oceans or rivers, and especially helpful for making farms, as you can now put the water needed to obtain wet farmland in the center of the farm, and still be able to easily access your crops without wading through water.

Lily Pads can also be used to create floating platforms, or waterborne bases in the ocean, as the player can place a lily pad on the water, then other blocks on the lily pad, rather than having to swim to the nearest landmass to create bridges.

It is possible to put lava on a lily pad. The lava destroys the lily pad but forms a five metre diameter disk of stone in the water. Retrieving the lava requires some fancy foot work and a few blocks but is possible.

History
Lily Pads were introduced in the Beta 1.9 pre-release. In Beta 1.9 Pre-releases 1-5, lily pads could only be placed on swamp water, and could not be walked on. But as of Beta 1.9 Pre-release 6, lily pads are now solid. This means that all entities can interact with the lily pad block: arrows stick to it, mobs can walk on it, and boats can collide with it. Like the Torch, a Slab, or any other Non-Solid, it causes falling gravel and sand to become a drop. But as of Beta 1.9 Pre-release 6, entities such as the Player cannot swim through lily pads to the surface.

Trivia

 * Lily pads are destroyed when the water beneath it freezes.
 * Lily pads are destroyed when water flows on it. This can be used to climb by alternating the placement of lily pads and water source blocks without leaving the placed lily pads.
 * Even when swimming under water, lily pads can be destroyed with one hit.
 * When lily pads are placed on water source blocks that do no take up the space of the entire block (when the water is flowing to the block next to it), the lily pad will appear floating above the water source block.
 * When placing a lily pad under another lily pad beneath the water, it destroys both lily pads and the water source blocks adjacent to the one the lily pad was placed on flow towards it; a lily pad can no longer be placed on this block, but can be placed on the adjacent water blocks flowing towards it.
 * In some lighting conditions, lily pads are less visible than other blocks when viewed from underwater.
 * Lily pads will act like blocks, making possible to walk over it.
