Skatole

Skatole is a passive item.

Effect

 * All types of flies except Boom Fly, Red Boom Fly, Sucker, and Spit become passive and slowly move towards Isaac. They will not fire at Isaac but will still cause contact damage. Isaac is also still vulnerable to the blast shots from Sucker and Spit flies.
 * Boom Flies and Red Boom Flies can still harm Isaac, but move much slower.

Trivia

 * Skatole is a mildly toxic white crystalline organic compound that occurs naturally in feces.
 * Skatole was considered as a cosmetic hat for Team Fortress 2, alongside tears, Brimstone, and Tiny Planet. It was dropped as Valve "... didn't want players running around with a wet piece of poop on their head."
