Bounce pads for CraftBukkit servers.
None! Just drop the jar into the plugins folder and play!
Bounce pads are essentially trampolines, to set them up you place a stone pressure plate on top of a block of mossy cobblestone.
The power of the bounce depends on the amount of mossy blocks underneath the pressure plate, up to a maximum of 3.
