There was a robot by the door.
There was 2 vampires.
The robot said 12 then the first vampire said 6 then the door unlocked.
The robot said 6 then the second vampire said 3 then the door unlocked.
Then Owen challenged the robot.
The robot said 4.
What is the answer?
4, because the word "FOUR" has four letters. TWELVE has 6 and SIX has 3 letters.
