A mysterious message posted earlier this week by McDonald's has officially been revealed, just in time for the cold weather to roll in.

The pink, blue and purple holiday cups featuring Doodle characters in snowy scenes will be available starting on Nov. 18. Doodles began as an NTF project made up of colorful pastel characters by artist Scott Martin. Many fans used their Doodle as a profile picture on social media. McDonald’s customers can earn digital and physical products.

McDonald’s is getting in on the holiday cup craze with a partnership with animation content company Doodles. The burger chain on Thursday posted to social media an image of a McCafe x Doodles holiday cups.
