If anyone was to wonder why Denzel was being so quiet, one doesn't have to look further then the basement of the mansion. Inside the workshop, Crocker has been staying up many nights, considering all of the spilled coffee mugs on the floor, trying to reconstruct a device. A rather
strange and almost
GhostBuster like. Next to that is a snowball catapult, that has been completed. If the smell of spilled coffee or Crocker himself from lack of bathing doesn't help you find him, then the excessive insane ranting echoing though the basement may help.
