Inverse Creepers

Adds new type of creepers to minecraft. Inverse Creepers are purple, and only spawn in forest biomes. they do not attack players, but run away from them. They attack ocelots and cats instead. when Inverse Creeper explodes, the explosion will not destroy blocks - but create blocks! There is a small chance those blocks will be ores. В§eWARNING: if the gamerule mobGriefing is off, inverse explosion will still create blocks, but wont replace existing ones. so basically, it wont ruin buildings, only "fill" them
