Please help, I can't remember it

I'm pretty sure that he watches over Mt. Ihu for Rahi and stuff like that.

I don't quite get what you're saying. his role in the storyline was being part of the chronicler's (Takua's) party that went to the Kini Nui if that's what you mean.

No, he asked what he does at Ko-Koro, like Jala is the guard leader in Ta-Koro.

Uhm didn't he translate what Nuju said ?
So that the other Ko-Koronans would understand ?

Kopeke really didn't have an aparrant job. He probably hanted rahi or guided the north march. Oh and "Bohrokbaby" that is matoro whom you speak of

i always confuse those two

I don't believe Kopeke has any real purpose. I believe Lego just put him in the MNOLG just so that you could have a Ko-koran to go with you to Kini-nui.

I think that I belive what XK said. Kopeke was probably just put in there so you could take him to Kini-Nui!

Moving to Theories...

Kopeke is an artist with ice.He's an ice carver.He can transform a single block of ice into many things.From a pretty delicate flower to a small statue of kopaka,perfect in every detail.Nuju said this in the MNOG.I'm surprised none of you said that.
