DieSheep is a fun and unique way to prevent people from getting dyed wool from sheep. For example, if you wanted to create a map which required you to collect wool of each color, but don't want sheep to provide any colored wool.

DieSheep changes all sheep's colored wool drops to white and then penalizes the player for trying to get colored wool.
You can set the worlds that this works on and the explosion damage in config.yml.
I created this plugin for a specific person a while back mostly as a joke. I never released it until now because I honestly didn't think anyone would want it, but figure I'll put it out there and let the people decide. If there is enough interest in this, I'll be updating it to be more customizable.
