Dec. 17, 2020 Jack in the Box is putting a new player in the crispy chicken sandwich foray with its newly introduced Cluck Sandwich featuring pickles and what the brand calls a "mystery sauce" on a brioche bun. To celebrate the launch, Jack in the Box has partnered with singer and actress Becky G to create a brand new chicken dance for fans to learn and share on social media, a news release said. To add to all the clucking, customers who share their dances using #JacksNewChickenDance between now and Valentine's Day will see Jack in the Box give a dollar to No Kid Hungry, up to $100,000.
