I was talking to Lady Kopaka last night, and as we exchanged ideas, we suddenly hit upon our very first collaborated, and possibly true, Bionicle theory.

The Zamor are actually bald Tribbles.

Proof:

Greg said the Bahrag made the Krana, which were a form of projectile, and both Krana and Zamor are available in green. Obviously, the Krana are some form of squishy mutant Tribble, which the Bahrag enslaved through telepathic suggestion and forced to command their Bohrok armies.

As everyone knows, the Tribbles multiplied quickly. Just like the Tribbles, you drop a Zamor, it will multiply into several hundred little shards.

Since Makuta is the master of disguises and full of sneaky plans, it's entirely likely he at one point infiltrated a Klingon warship under the guise of an incredibly believable walking shrub. He can't stand the light, though, so as he snuck through the cargo hold in the dark, he probably would have stumbled across a Tribble or two stowing away under some packing peanuts. Being as he finds evil uses for everything, he tucked a few away in his pockets. He most likely later shaved the rapidly increasing number of Tribbles at his lair, to save himself the trouble of daily brushings.

Further proof:

If you'll look closely, you can make out the faintest suggestion of a nose in the Zamor's colorful swirls, but it's a common fact that nobody has ever spotted a fuzzy Zamor.

Although Makuta was quite inconveniently crushed under the door by Takanuva's sneakiness, Greg said he wasn't killed. But, to keep his essence from drifting out of his smashed armor and dissipating, he would have used his remaining strength to drain his essence into the nearest living beings: The Tribbles. His green essence dyed them green, because everyone knows nothing green ever dyed anything blue or orange.

When the Piraka came onto the scene, they would have obviously been no better than any Matoran at resisting the Tribbles' adorable squeaks, and took them out of the lair with them. Through the Tribbles, Makuta telepathically transmitted his plan for them to get the Mask of Life.

Once the Piraka arrived at their fortress, they found they were low on projectiles (probably because they hadn't made any yet), and were at a loss as to what to do until Avak hit upon the brilliant idea of launching the handy Tribbles. Being stuffed into the launchers startled the Tribbles into silence.

As for the large container of green stuff, that's just a prop made by Zaktan, which he tries to make convincing by talking to once in awhile. After all, if you were a former Dark Hunter and planning to steal one of the universe's greatest masks, would you want anyone to know you fell for the cuteness of a ball of fuzz?

So there you are: eight whole paragraphs of proof that the Zamor are actually bald Tribbles.
