Harry Claymore is a former special effects master and claymation animator.
Proclaimed as a master animator, Claymore utilized black magic to allow his clay figures to animate themselves, thereby greatly decreasing the difficulty of painstakingly moving all the puppets by hand. However, upon the popularization of CGI animation, the creations were driven insane by the public's lack of interest in stop motion animation, enslaving Harry and sending his home into disarray.
In the "Little Gift Shop of Horrors" story, "Clay Day," the Pines family and Soos come to his home hoping that he would explain to Mabel, who feared claymation, that it was nothing to be afraid of, only to find him tied up with his clay figures walking on their own. He then explains to them about how the clay figures went crazy because of the rise of computer animation, thus having no need for them. Thanks to Mabel, the clay monsters were dealt with, freeing Harry.
Harry Claymore appears to be very elderly, as he has gray hair and various wrinkles across his body. He wears a red long-sleeved polo shirt with a pale blue collar, tan pants and brown Bermuda shoes.
