If you want a NPC Plugin you guys have to promise not to abuse it like mobdeguise >.> with spawning alot of NPC's for one thing...
NPC plugin is called NPCWarehouse with no MySGL required or Spout require! ^_^ and it automates the NPC skin to whatever you called the NPC name! (the name has to be registered with Minecraft/Mineshafter to get the skin
)
