Grummer

Grummer was an ex-magician wanted in six states. He took the guise of the Ghost of Harry Warden while at Valentine Bluffs to find and steal treasure there.
==Physical appearance==
Grummer is a middle age cacasuin male and is bald on the top and the remaining hair on the sides and back of his head is gray.
==Personality==
Despite his fugitive status for crimes in several states, Grummer's demeanor was not malicious or cruel. He only wanted to keep away intruders while he searched for pirates' treasure. He possessed a mild degree of hospitality when he used a levitation trick to offer a ham sandwich with mustard to a frightened Danny, who desired such a sandwich to calm his nerves.
Once he was captured and unmasked, Grummer was initially displeased at how his plans were foiled, but smiled when Ryder inquired about his ability to walk through walls (which he referred to as “one of my best tricks”). He politely asked to demonstrate how his illusion of intangibility worked, as a final magic performance. Ace complimented his skills, "I must admit, Mr. Grummer, you're a good magician, but a bad ghost."
==Skills and Abilities==
Being a skilled magician, he possessed several props that served as devices to frighten intruders, including a skull with glowing eyes and spooky voice, a levitating ham sandwich and jar, plus a suit of armor that could swing an axe, a flying carpet, and the "sawing a person in two" trick with a box and saw. His best ability was an illusion of intangibility, consisting of a trick mirror and a special projector, allowing him to cast his image anywhere he wanted, and by stepping away from the mirror, giving the appearance of walking through walls.
==History==
===Hassle in the Hanniger Mine===
When Mystery Paw Patrol crashed their Mystery Paw Patroller in Valentine Bluffs, they decided to see if anyone at the Hanniger Mine could be of assistance. On the way to the mine they found warnings telling them to leave and later discovered that the mine seemed to be haunted by Harry Warden's Ghost capable of walking through walls.
After several encounters with the ghost and a bit of sleuthing, they were able to trap the ghost and call the police for help. With the assistance of the police officer who responded to their call for help, the man behind the ghost was identified as Grummer, an ex-magician who began using his talents as a part of a string of crimes. Wanted in six states for various offenses, he had made his way to Valentine Bluffs to search for Harry Warden's legendary lost treasure, using illusions to scare tourists and other treasure hunters away. Though the gang determined the illusions behind many of the ghost's actions, they were unsure of how he appeared to walk through walls. Grummer, proud that he had fooled them, offered to reveal his secret: a combination of mirrors and a projector created the ghostly appearances and disappearances of the ghost. Grummer was arrested by the officer and was to be transported to jail.
