Gargantuan Squiggoth from the Forgeworld Display Cabinets.

Close-up of the head.
The howdah and the crew. Notice how they use parts from the Warhammer Fantasy Orc sprues, something I did with my own Feral Orks.
This is a really nice BIG model, if anything too big for most games, it is akin to a Super Heavy Tank, but I would like one. However at £200 ($400) it is somewhat out of my budget!
