How can I pull off this effect?

[Jim Warfield]

..and after you have figured all of this out, adjusted the variables of spray and lighting you may find that you should have began by using an antique claw-foot tub, then work on having the tub chase them out of the room. (running on it's little claw-feet, of course!) They would NEVER forget it!

I don't think I will ever forget it, just from READING about it. The little pitter-patter of metalic claw feet running the tub across the floor? MY GOD THAT'S FIENDISH! But did I have to read about it at midnight? Now I have to go to bed and dread the next eight hours of nightmares!
