The lightning creeper wolf looks like a creeper but with a blue charge. To tame the wolf don't right click it or else it will explode and kill you. Instead you need to craft ten gunpowder bones by putting one gunpowder with one bone in the crafting table any way you like. This will give you 2 gunpowder bones. To tame the wolf throw the bones out of your inventory and the lightning creeper wolf will go after them. To know that the wolf is tamed you'll notice the sad face turns into a happy face. When fighting and your wolf is taking damage the blue charge around it starts to fade. This signals that your wolf will need to heal soon, so you need a lightning helmet. To craft a lightning helmet you need one iron ingot on the top middle slot, one gold ingot on the bottom middle slot, and a iron helmet in the middle slot. This will give you a lightning helmet. To heal your wolf, just put the helmet on your wolf. You'll see that his blue charge starts to come back. Just be aware that you could use the helmet only 30 times. To find the lightning creeper wolf go to the new lightning biome. You'll know your in the lightning biome because of lightning trees, lightning grass and dirt, etc. This will make Minecraft better because it adds a cool new mob, a new biome, and two new items.
