I have one more of those pieces and a Takadox head, but those were meant to be the only blue parts, like on the original 'Ramas.
I know the originals were bright, but I like to make monochrome MOCs so I don't have to worry about colors matching or having the right parts.
Yes, I have a few, but only in dark blue, dark red, and grey. Any of those would have been weird to build with, and I wanted a completely different construction than the set.
