Fuel Dock

are specifically areas in which Fuel Items can be placed. Unlike the much-related, do not have a set model/animation.

Uses
are utilized whenever an Item or the Blacksmith's Smeltery require a Fuel source in order to operate. Any Fuel Item can be placed within it exactly the same as Docks, though usually do not possess any form of ejection, therefore their contents must be completely consumed before any new fuel source may be utilized.
