Holiday Knights (part 2)

December 22 In Mayfields Department Store, Barbara is just purchasing a new tie for her father when all of a sudden an ear-piercing wail cuts through the air. The shop attendant comments on how they've been crying all day, at which point we see why: Harvey Bullock is playing Santa. With his partner, Montoya, he's on a stakeout. Bullock, showing rare sensitivity, comforts a young girl who's father he put in prison, and winds up giving her cash to soothe her Christmastime woes.
Barbara, walking through the store, happens to spot a child shoplifting, but when she tries to apprehend him, his clothes and hand seem to dissolve into nothing. Then, Montoya gets a call through her earpiece that detectives are in pursuit of four child bandits in the store. Just when the children seem to be trapped, they meld! Moments later the truth is revealed: Clayface! He begins tearing up the place and no one can stop him, that is, until Barbara gets changed into her Batgirl outfit and delivers a blow to the head the sends him crashing out the window and into the skating rink below. Montoya and Bullock arrive on the scene and with a little guidance from Barbara, succeed in halting the giant shapeshifter by way of electrocution.
