Honey Block

Honey blocks are sticky blocks craftable from honey bottles.

Usage
Honey blocks slow down entities walking on top of it and prevent them from jumping. Entities touching the side of a honey block will fall at a slower speed and will not take fall damage, similar to going down a ladder.

When pushed by a piston, entities on its top surface and adjacent blocks when pushed by a piston. Mobs will not be launched high in the air if a piston pushes them up, unlike the slime block's behavior.

Falling onto a honey block reduces the fall damage by 80%, i.e. the player or mob takes 20% of the normal fall damage.
