MWF Submarines are possibly built by Finnwich, as he built the Cleaners, Reaper Mats, Blue Reaper Mats, Steam-Mats and Eyebots. They appear to transport any Coral Grove Prisoners to and from Coral Grove after picking them up from an MWF Van.
They are white and have the Mann, Wurst, Finnwich Logo on the top of the entrance hatch. The inside is decorated with the signature MWF green. It houses many crates that the prisoners are in.
Game of Clones: It made its second appearance in Game of Clones.
