So..
I'm going to explain some things regarding my theory.
First, Verdigris has amazing wall-jumping ability. However, he can't wall jump on spikes. He can wall jump, as long as he's slightly brushing against a wall. He can go to his room just fine. Also, he can get to half of the screen by double-jumping.
The long leg thing... do you want to hear it?
Oh, and is there a single piece of music by Nintendo that suggests Mario is gay? One that is used in a level? Did Terry not check the room names of the screens in his game?
I'm assuming Verdigris is a green dude, because he's the only green dude in the main game of VVVVVV, and the only one intended to exist.
Captain Viridian has no way of knowing when the player would want to use the abilities Verdigris has.
And just because it's a reference doesn't mean that it was real.
Just saying what I think.
Feel free to say what you think, but remember that this is supposed to be a friendly discussion.
