Arachnorod Hot Wheels. A die-cast 1:64 scale model hot rod. It gets its name from the combination of the words “arachnid” and “hot rod” because the car’s engine has a spider-like appearance. This collectible was released in 2003 in honor of Mattel’s 35th-anniversary. It is marked as collector #120. Because this Arachnorod Hot Wheels has never been removed from the original box, it is in mint condition.
