Shake Shack in Westport held a special Donation Day on Tuesday.

The location donated 25% of customers' total purchases to the Cancer Couch Foundation and the mombies were there to help.

The mombies are a group of moms who dress up and dance as zombies all while raising funds for breast cancer research.

The group is hosting the Mombies Mother's Day 5k Race on May 11 at Jennings Beach in Fairfield.

News 12 is the media sponsor of the Mombies Mother's Day 5k race.

Optimum is also a proud presenting sponsor.
