Leatherface: Texas Chainsaw Massacre III · Played by Joe Unger
Story spoilers
In the story
Tinker is a member of the household encountered by Michelle and Ryan. His presence adds another specialized personality to the family rather than leaving all of its menace to Leatherface.
Continuity matters
Marketed as the third installment, but its family configuration and references do not form a seamless continuation of the second film. Release order is clearer than a single literal family timeline.
