The Jack-in-the-Box is a special tactical grenade that is found in Call of Duty: WWII Nazi Zombies. It can be found in the Mystery Box on the maps Prologue, The Final ReichGröesten Haus, The Darkest Shore, and The Shadowed Throne. When thrown, it will attract any nearby zombies to the device, very similarly to the Monkey Bomb from Treyarch Zombies. When the song playing from the box finishes and the "jack" pops out of the box, it will explode.
