Green poo was one of many colorful ways brands celebrated on Twitter this week, alongside smiles, teachers, and all day breakfasts.

The Martian may have premiered in September, but this week, NASA effectively used the movie to further drive its sharp social media and content marketing strategy to the next level. Using a video interview with the movie's female lead, Jessica Chastain, NASA also promoted women in space.

  Here's what competitors had to say:

Dunkin' Donuts used the hashtag #BreakfastWhenevs to shift the dialogue with this Tweet:


Not to be left out of the hamburger wars, Burger King launched its black-bunned Halloween Whopper. It got more than it bargained for though when #GreenPoop began trending in the U.S. on Wednesday evening.

@BurgerKing and #HalloweenWhopper garnered over 14,000 mentions and 121,000 engagements by October 8, according to Talkwalker.
