Partial (does not block light, mob spawning possible)

|“||Slime blocks can be used to bounce on, like some sort of snot-coated trampoline. The height of your bounce is relative to how far you fall onto the block. So if you say, fall six blocks of height and land on a slime block, you'll bounce four blocks high into the air! Wheeeeee! While this is a lot of fun, it does also mean your feet touched a slime block. You might want to burn those shoes. And those feet. Better safe than sorry.||„|
The slime block is a transparent block with unique properties.
Slime blocks can be broken instantly, regardless of held items.
Landing on a slime block won't cause fall damage unless you are sneaking.
An interesting quirk of slime blocks (and end portal frames and monster spawners) is that they are transparent in their rendering only – unlike most other transparent blocks, they can have torches and redstone placed on them, conduct a redstone current, will suffocate mobs, and more.
Slime blocks cause movement on top of them to slow down.
Slime blocks will cause players and mobs to bounce at a height relative to the velocity. The bounce height quickly deteriorates. For example, a fall of 255 blocks only produces a bounce height of about 50 blocks, while a fall of 50 blocks is a bounce height of 22 blocks. The maximum jump height is around 57.5 blocks.
If the player is holding the jump key, they will perform a normal jump on contact with the slime block without taking fall damage. If the player is holding sneak, they will not bounce at all, although they will take fall damage.
Placing carpets, rails, trapdoors, redstone repeaters or redstone comparators on a slime block does not stop mobs from bouncing and not taking fall damage. Likewise, placing a pressure plate on a slime block does not stop mobs from bouncing, but the pressure plate will activate. Cake, slabs, and other half blocks stop the bouncing effect.
Dropped items move quickly when in water that is flowing over slime blocks (although slower than they do over ice). This is particularly useful for transporting resources using water currents because items will keep sliding on slime blocks when they are dropped at an angle, even if water is not placed on top. Due to slime blocks not melting, unlike normal ice, they are far safer.
When being pushed by a piston, entities (except ender dragons, item frames and paintings) that are ahead will be launched into the direction the block is pushed into. When pulled by a piston, no entities are launched. If an entity is on a moving slime block, it usually falls into or through that block, unless the block is being pushed upward.
When a slime block is pushed or pulled by a piston it will attempt to move, in the same direction, all adjacent blocks. The types of blocks that can be moved are the same as those that can be pulled by a sticky piston. Blocks that can not be pulled by a sticky piston (i.e. all the blocks listed on the table on the pistons page) stay in place. The blocks that are moved may in turn push other blocks. For example, a slime block sitting on the ground will attempt to move the ground block underneath itself, which will in turn have to push additional ground blocks in the direction of motion just as if it were being pushed directly by a piston.
Glazed terracotta is an exception; it will not move when adjacent slime blocks are moved.
When the adjacent block that is moved is also a slime block it will, in turn, try to move all its adjacent blocks. For example, a 2×2×2 cube of slime blocks may be pushed or pulled as a unit by a single piston acting on any of the blocks in the cube.
A slime block adjacent to a block that cannot be moved by pistons will ignore the immobile block. But if an adjacent block could be moved but is prevented by the presence of an immobile block, the slime block will be prevented from moving. Liquids are an exception: they aren't moved, but neither do they stop a piston from pushing or pulling blocks into their space (usually destroying the liquid, and in a rare case displacing it through the piston).
Slime blocks are not pulled by a non-sticky piston, nor are they moved if an adjacent (non-slime) block is moved by a piston.
The maximum of 12 blocks moved by a piston still applies. For example, a 2×2×3 of slime blocks may be pushed or pulled by a sticky piston as long as no other movable blocks are adjacent to it.
A piston cannot move itself via a "hook" constructed of slime blocks, but self-propelled contraptions can be created with multiple pistons.

|Slime blocks pushed by a piston vertically will launch entities into the air.|
|14w19a||Slime blocks can now push entities sideways and downwards when attached to a piston.|
|14w25a||The texture of the inside block originally used the 10×10 center of the 16×16 slime.png file, however, since the addition of explicit texture referencing in block models in this snapshot, the center 10×10 section has its own texture, due to limitations of the custom models not being able to access non-square texture files.|

- Translucent blocks (blocks with two different transparencies), such as slime blocks, are now able to be implemented due to a new rendering system.
- A minecart leaving a rail onto a slime block will be able to continue on a rail on the opposite side, if it has sufficient momentum leaving the initial rail.
- Any entity landing on the sides of the block will not bounce. In order to bounce, you need to land on the top.
- Slime blocks under soul sand make the player move slower than if the player was just walking on soul sand.
- Rabbits will not jump while on a slime block.
- Entities launched upwards by a slime block on top of a piston will achieve slightly more than 6.4 blocks of lift, including the lift from the piston. Entities launched sideways across normal blocks or air will be moved 3.510 blocks in the direction of the launch.
- Placing a Slime Block quickly before suffering a tall drop will cancel all fall damage.
