Bullsquids always been my favorite in Half-life (after houndeyes) so I blendered one up. I based my take on the bullsquid on the original model with a few minor changes like the mouth. Proportionally it is nearly 1:1 to the original being just a little thicker in a few areas.
To accomodate the custom bullsquid I extracted a bunch of junk and props from maps and used Half-life textures to make a hazardous materials junkyard scene.
