Leatherface: The Texas Chainsaw Massacre III
Tinker first appears when Benny returns to his capsized car, passing the time by lighting flares. Benny asks for his help to turn his car upright and Tinker gets in his truck, presumably to push the car upright. When Benny looks in Tinker's truck to find an assortment of malicious tools, he believes Tinker to be a killer and runs to his truck to grab his gun. Tinker soon starts up his truck and rams Benny's car at full speed, sending Benny tumbling down the hillside. Tinker laughs on as Benny disappears into the darkness.

Tinker later returns to the Sawyer residence to greet his mother and Edward, dragging Ryan in with him. Him and Edward both hook Ryan to the hammer machine in the kitchen before Tinker begins setting up dinner. When Edward introduces a kidnapped and bound Michelle to him, Tinker accidentally refers to Edward by his real name, angering the latter greatly. Tinker apologizes for it and offers Edward the honour of gagging Michelle. Once she is gagged, Tinker leaves to retrieve 'Junior's present'.

Later, when Leatherface returns home and begins harassing Michelle, Edward brings in his present, which turns out to be a chainsaw that Tinker single-handedly crafted. After admitting his appreciation, Tinker comes in and begins scolding Leatherface for arriving empty handed, referring to how Leatherface was supposed to kill Benny and bring back his body. In a show of his outrage, Tinker takes Leatherface's souvenir, a Walkman, and tosses it into the stove, before he his suddenly choked by an irritated Leatherface. While choking him, Leatherface forces Tinker to reach in and retrieve the Walkman with his real hand, burning it in the process. With the Walkman destroyed, Leatherface runs to Mama for comfort, while Edward helps Tinker up and attempts to distract him from a potential fight with his sibling.

While Mama and Junior are setting up the dinner table, Tinker and Edward are releasing the hammer machine's mounted sledgehammer and bludgeoning Ryan. When Leatherface is preparing to mutilate Michelle with his present, Benny begin firing at the family from the window, hitting Tinker in the ear and ripping it clean off. Incapacitated and bleeding, Tinker commands Edward to kill Michelle before she escaped. What happens to Tinker from here is unknown.
