Halloween DEVIL CAN 1.2 born 2010 reborn 2013 repaired 2016
The can bounces up and down to attract attention.
The devil pops up and the eyes and the inside of the can light up red.
Compressed air can spray out the front of the can in case of curious victims.
Extremely loud Air Horn discourages lurkers and/or makes small trick-or-treaters drop their loot (a handy source of candy resupply).
The Air Horn is so loud it ruins the videos so it must be used in moderation. Some prop operators in the past have abused the air horn so a switch was added to disable the horn (if needed) and named after a particularly egregious offender.
