In Harley Quinn's twisted version of this lullaby, the lyric continues: "Momma's gonna kill for you the whole damn world."

The beautiful, deranged psychiatrist swings a mean baseball bat while on the prowl as a member of the Suicide Squad. Now that famous Good Night bat can be yours as a miniature replica on our key chain with an enameled Suicide Squad medallion.

Channel your inner Harley with this sweet reminder of Daddy's Lil Monster.

The keychain is made of soft PVC and silver plated metal. The creat measures approx. 7 cm.
