lol the first time I saw Regigigas, about 5 or so years after I played megaman x, the grass on its body reminded me of that level (Sting Chameleon) and the miniboss, but my memory was sort of cloudy. Then, I went to find the name of the miniboss and looked at the sprite and was like "wow, that doesn't look like Regigigas.... it looks like Registeel!"
