I just watched the latest episode, and I gotta say that I liked how you decided to demonstrate playing as Vezok, right after the "end" of the episode. How about the rest of the Piraka? (My favorite of the Piraka's weapons are Avak's, Zaktan's, and Vezon's.) Since you seem to keep wondering if it's possible to collect all five silver canisters in a level without any Piraka or upgraded Toa, I'll just say from my extensive experience that it is possible, but only on just three levels, if I remember correctly. The first is in Avak's zone, the second is in Reidak's zone, and the third I'm afraid I don't remember exactly, but I'm pretty sure it's not in the first three zones, which you're now almost done with.
