Bionicle MOC: Magmakrok

About the MOC This is another more simple MOC I made in about aday. But I did go back the next day and tweak it a little bit. The concept for this MOC came about from a conversation I had with my friend while I was still working on the Rhotuka Tiger. Not to mention its about all I could do after using the other set of caterpillar tracks for Isra's hair.
I'm actually rather happy with this Rahi. I think it looks like a crocodile or is recognizable as one, and that's what works for me. I Think over all its kinda gappy on the sides, but that's the nature of this build. Its a rahi with a tank trak for a body/belly. I had a panel on the front part of the track to cover it up and make the body look more solid, but it A) interfered with the movement of the front legs, and B0 covered up the track so that it was a little difficult to see the track and the movement of it and the gears when it did roll. And that wasn't nearly as cool. At this point the only thing I might change would be more articulate legs,i.e Hero Factory, but I didn't have anymore armor for HF in the right colors. And this works. I like the armoring of these matoran arms anyways.
Another notable feature of the Magmakrok besides its track is that its jaw snaps shut when the wires on its head are bent back up. So there's a bit of realism there, not to mention my signature style of incorporating functionality. It works the same way the old 2004 titan sets work, bend the soft axle one way and it opens, bend it the other way closes.

Bio
The Magmakrok is a somewhat aggressive Rahi found in areas where there are flows or pools of Magma. They're somewhat uncommon rahi. It is believed that they're a variation of rahi that most likely were trapped underground and adapted to the conditions. A few specimens of Magmakrok were added to the Onu-Metru Archives. Because of the rarity of these Rahi, no known case of domestication has been reported.
These creatures typically don't attack unless seeking prey or provoked. But they can mistake people for other rahi and attack without provocation. Most matoran would have difficulty fending these creatures off, but a Toa, Dark hunter or Makuta could easily fair with these creatures alone. The biggest danger though isn't the creatures themselves, but the molten protodermis or magma they fling and splash around in their attacking, then the residual heat they retain from being in the magma. For these reasons they can be quite dangerous for any creature.
On land they can be surprisingly fast in short bursts using their track bellies to traverse the land much faster than their short legs would be able to carry them otherwise. In magma or molten protodermis, they use their tails tracks and legs to swim through the magma.
Magmakroks mainly eat Infernavika, Ranama. and Lava Eels, but most any rahi that find their way near magma pools or flows may be attacked if the Magmakrok senses its size isn't too large. The only known natural predator to Magmakroks are Lava Apes and the fire variation of Vako

I watched this pretty cool video to get inspiration on my MagmaKrok. You should watch it, its quite informative and interesting.
