Heinz Ketchup has rebranded as Tomato Blood Ketchup for a limited-edition Halloween packaging run, is offering themed merchandise including Tomato Blood costume kits and has opened a Los Angeles Heinz Halloween Store that features “drip stations” to let visitors decorate costumes. A short spot from Wieden+Kennedy New York introduces the Tomato Blood Ketchup with the copy, “If you have Heinz, you have a costume,” and the brand is encouraging fans to share their costumes on social media using #HeinzHalloween.
