For back to school season, Crayola is partnering with Kraft to produce more than 2.5 million limited-edition boxes of Kraft Mac & Cheese. These boxes feature the traditional Kraft design, but with blank space for kids to draw and color.

Parents can share their kids’ creations with the hashtags #KraftMacNColor and #Contest for a chance to have the design officially printed on a Kraft box and sent to them. The companies will choose 100 winning designs based on originality, colorfulness, and overall creativity.

For additional ways to play, there are videos at that show kids how to turn the boxes into creatures, such as a hedgehog, a dolphin, or a giraffe.

“The impact of back-to-school activities and routine puts extra pressure on parents getting kids and dinner to the table,” says Anne Field, senior director of marketing for Kraft. “These amazing boxes are one way we can help make parents’ lives easier, by giving kids a fun activity while the Kraft Mac & Cheese they love is cooking. We’re excited to bring two of the most beloved brands of parents and kids together to make mealtime a win-win for everyone.”
