The Blue Sprocket (or something like that)

Found another clue from the lost 6th Borough of NYC by the BQE in Cobble Hill! Calculations point toward it being a missing component from a taffy machine that operated in the now defunct Zephyr Candy Factory years ago.

This harmless artifact led to a giant argument in the Apartment. Frankie claims it’s a Sprocket, while Sudsy the ghost insists it’s a Gear. Bill the Snowman thinks it’s a Cooling Fan. Mr. Parfenix repeated that it’s a Blender Blade (“Blender Blade, Blender Blade, Blender Blade”). Computer Head mumbled that it might be a Computer. To me, it looks like Garbage. What do you think it is?
