If you're having trouble making this work, it's likely because some of the wolves are getting away and that can make you evil. There are several things you need to do to make this work - in 20 minutes I had a rainbow hand and a spanking white temple. Also, Megablast Extreme doesn't kill all the wolves and can make you evil. Use the lightning.
First, demolish the water miracle dispenser - it takes two full blasts of mega lightning to do this. If you don't demolish it totally villagers will come to rebuild it. Then get rid of all the teddy bears up on the plain on the mountain. Then kill all the pigs with the lightning and throw the bodies into the water. Why do all this? Because these things all attract the lightning, and some of the wolves get away. Once everything is out of the way, position yourself between the wolves and lightning dispensers, facing the open plain. Cast the wolves just in between the dispensers and quickly grab your lightning. Then blast the wolves with the lightning.
Repeat this for about a half hour and you can't get much holier. There are rainbows in the sky, on your hand, and a beautifully white temple.
My recommendation is to do this before you get your creature; depending on what habits you want him to pick up. I want a good creature so I try to go easy on the evil miracles with him.
