Thank you for the kind words, everyone!
Why does that keep coming as a surprise to people?
To be honest, they're not very functional as swords, either. Rather, they function more as extra pincers, but I forgot to include an "attack" picture. I might snap and upload one later. :-)
Well, given I had to work with what I had left, there wasn't much of a choice. I'm still not 100% happy with how it turned out, but it fits and the vines/tentacles add a nice touch when it's inside the Bohrok.
It's probably possible, as there are quite a few gears available. I'm not very technically inclined, so I'm not sure I'd be able to figure it out, though. My MOC designs usually lean more towards shape/appearance than actual functionality. And as I mentioned, I was too lazy to take apart the Toa gear mechanism. :-s
