My tier list S: Ring, Roof, Subway A: Incinerator, Girders, Grind, Buoy B: Lighthouse, Towers, Chutes, Vents C: Trucks, Gondola, Blimp, Containers D: Train, Trawler, Wheel, Aquarium, Billboard (I HATE FISH CREATURES AND WATER BRO AND MAPS YOU CAN HARDLY FIGHT AND MOVE ON)
theres no evidence to suggest that the guy in the billboard ad is controlling it, or that the griders are supposed to grind up people, but i think if your theory is correct then the grinded up gang beast guys probably turn into the goo first before being made into the suspicious sausages
