Tudor's Biography[]
As a young boy, Gregory had witnessed his local ice cream man, Butch Brickle, being murdered in a drive-by shooting. The young boy was left upset by the incident, seeing as he idolized Butch and saw him as one of his heroes (calling him the "Ice Cream King").
Some time after the incident, he had also suffered abusive treatment at the Wishing Well Sanatorium, in which the orderlies happened to be just as insane and unstable as the patients they were treating, and would constantly force Gregory to "be happy". Throughout the film, Gregory is shown to have nightmares of his days at the sanatorium, and he also frequently and obsessively visits the grave of Butch Brickle at odd hours of the night.
Eventually, Gregory became an ice cream man himself, and started working in the same truck and ice cream parlor that Butch had used before he was killed. However, unbeknownst to his customers, he would place gruesome ingredients in his ice cream delights, such as insects and body parts obtained from his murder victims. He would also use the dilapidated ice cream parlor as a sort of laboratory in which he produces his concoctions.

Gregory covered in blood.
Death[]

Gregory's death.
Gregory's demise comes in the form of a group of kids known as the Rocketeers, consisting of Roger, Johnny, Heather, Tuna, and Small Paul. The latter of these kids places Gregory into a hypnotised trace by holding a photo of Butch Brickle over his face, leading Gregory to walk into a trap that pulls him into the main ice cream mixer, where Gregory is shredded by the razor-sharp mixing blades.
James gave this death the "Dull Machete" award because he thought it was underwhelming.
