If so, it's probably story-related.

TBH the penguin (platypus?) form may cause me to pick up the minipla, at least. One of my favorite mecha conceits in a long time.

I don't have any of the DX stuff. does the top half of Tyramigo just pop off so it can be replaced, or is that some sort of armor that sits in front of it? If so, it'd likely kill the arm articulation.
