As someone who's watched MST3K's "Prince of Space," I can tell you that the Japanese used to have their own struggles with accommodating anatomy.
Is that the one where I've seen the photos of the Megazord with the giant train boner? What's the deal with that? Does it make sense in context or is this one of those cases where I just have to shrug, shake my head, and mutter, "Oh, Japan..."?
Here is the scene
BTW Zyuranger is on Shout factory's website. Curious to hear your opinions on it!
