Behind the scenesEdit
J-4CK was a droid purchasable in the Star Wars: Clone Wars Adventures video game. It was able to be purchased exclusively during Halloween time. J-4CK appears like the name Jack. Given that the droid was described as having a "Droid-o-lantern" smile, this is likely a reference to the real world jack-o'-lantern.
