Here’s the animation for the walk-cycle of the monsters. The rough, front two legs at least. The middle legs will just swing loosely, and the hind legs will work similarly to this.
If they don’t move automatically, click them and they will.
…And here’s the fire-lighter gas container (Gaseous Material Containment Unit for short). Any resemblance to a fire extinguisher is purely coincidental.
This one will animate when clicked on as well.
