Flying On The Wrong Side Of The Street Purple_Dave: Anton Mokhov is the person who actually came up with this idea, though his friend Taras Kamtchatnikov submitted it. Basically, all you need is the two purple PAKARI and two of the heads with yellow eyes from the NUI-JAGA set, plus a pair of #2 plus-rods. Stick the plus-rods in the forward facing holes on the top pair of blue shoulder/hip joints, attach the heads to them via the yellow eye-pieces, and stick the MASKS on. That's it. Now your KAHU is batting for the other team.
Taras Kamtchatnikov also submitted a few color changes of his own to go with this modification. Replace the white ONUA claws with black ones, and make the eyes completely red.
