Kopaka shares the same basic build as Tahu but now has a silver sword. Gali and Pohatu have two 1x1x1 2/3 bricks with side studs to make up their faces. Lewa’s face has a 1x2 brick with side studs in green and a 1x2 green bracket. Gali and Pohatu also use angled axle connectors in place of the macaroni pieces due to the coloring (they could also be 90 degrees). Onua has two gunmetal macaroni pieces for arms but they are close enough.
A big part of the appeal of the Tahu is that it’s built with a limited selection of existing pieces in existing colors, and going digital cheapens that somewhat. I would like to see that Kopaka replicated, but it’s physically impossible to do so, along with the Lewa, Pohatu, and Gali.
Yes it is unfortunate that they cannot be built in this state. However I tried to keep the style similar. The main issue is that they used those macaroni pipe pieces for arms and those exist in limited colors. There are some other pieces such as the top of Pohatu’s head that strangely do not exist in the right color but overall it’s pretty close (if you’re willing to give some of them silver weapons). I could make versions that can be built from existing parts but mostly it’s just waiting for the right colors for the macaroni pieces.
