A slow moving tank blimp. Patchy rope cover balloons would carry it aloft with wooden windmill props at the rear. Since it would be manned by skeletons the bottom portion would be an old wooden ship. Fires out a mortar/cannon splash damage effect with low dps. Primary use would be to soften up buildings and walls. This would be a high level townhall troop and would support ground troops mainly. Could take place of lava hounds or dragons at townhall 10 or so.
