This is my modified version of the GHEKULA , from the Build It section of the online LEGO® Club.

The biggest complaint that I had with it was how the BOHROK faceplate could just flop open and send the KRANA flying, so I added a couple of the perpendicular connectors used to attach the hips on all of the BOHROK VA except GAHLOK VA, and one of the #3-length light-grey loose pins used to attach the faceplates on the BOHROK. Since the hip-joints on the back legs are attached with #3 plus-rods, all you have to do is slide them out a bit to attach this rig. As you can see below, this design allows the faceplate to open up like normal, though there really isn’t anything to trigger it like on a BOHROK.

I also didn’t like the widely varied coloration, so I swapped out the light-grey brainpan with a green one from LEHVAK VA and a PAHRAK XA replaced the GAHLOK XA, resulting in a nice uniformly green back. Well, except for those black BOHROK skull pieces. And the blue GAHLOK torso pieces. (Hey, as soon as LEGO® makes green GAHLOK hand-shields, I’m swapping out all of the blue parts…)

Anyways, I also swapped out the LEHVAK eye used for the mouth lever with a TAHNOK eye, which blends in a lot better. Also, since I had left an open spot in the middle of the peak of the back, I stuck a pair of green 1×3 flat liftarms in to replace the faceplate mount, so the back doesn’t squeeze together anymore.

I also found that the skull pieces used to form the lower jaw tend to drift inward, so another pair of those green 1×3 flat liftarms helped out there as well. However, since I actually have better uses for those, I ended up replacing them with a single black 1x1x3 liftarm (used for BOHROK VA hips) which works just as well, since you can’t really see it anyways.

Finally, a second LEHVAK VA brainpan fixes the coloration of the jaw, and a TURAGA hand with a piece of Darth Vader’s lightsaber gave me a tongue that’s not only longer, but more symmetrical. Besides, if I want, I can always add on a few more lightsaber pieces to extend the length of it quite a bit.
