Common physics prove that you can't freeze something thats on fire because the fire would melt it really quickly. So while common physics are doing their jobs I go get my flamethrower and I use it to kill the Water Ninja.
@gtfawjkjg (Where the genades on fire?) The ninja runs away from the flame thrower and jumps onto a metal building. He then shoots water out of his hands at gtfawjkjg.
