Progress Update: Spikes Unveiled

I've decided what the tusks are going to be used for: Spikes. They can be placed the top,bottom, or side of most blocks, including pistons. Even cooler is when they are placed on fences. When placed on wooden and nether fences they form small pikes that give the look of a palisade. On Iron Fences, due to their continuous surface, the spikes form a continuous strip in what reminds me of police spike strips.

At the moment they do 2 damage when any entity comes in contact to them. If they are clicked on with a slime ball or poison droplet (which now drops from lizards) the spike will become a Sticky or Poisoned Spike respectively. Stick Spikes, in addition to doing damage, will also slow the entity that collides with them. Poison behaves the same except it obviously applies a poison effect instead.

This video quickly shows off everything I'm describing.
