But it wasn't until I tried to beat VNOLG a second time with Hewkii (which I am close to doing, by the way), that I realized how lazy he was. All the other Matoran did something. Garan wandered the ends of the island with you, as did Kazi. Dalu and Balta made you very awesome armour, and Velika made you cool tools.
But what does Piruk do? He sends you all over the island with errands, mostly involving his pet Burnak. If anything, his burnak was more of a hero than he was. Lazy sod.
