Ok, I wanna answer some!
8. I don't think any of the Mario characters are gay.
9. He doesn't HATE Mario, per se, It's that Bowser has an evil plan to tak eover the world and Mario keeps ruining it.
10. They were bored. Seriously though, As the Mario universe expands, new characters are needed to fill these expansions (which explains Waluigi.... ;-) )
11. Cuz he's a lazy bum.
12. Even I can't tell you this one.
13. Ummmmm the video game characters kept arguing over which one was the biggest star in Nintendoland, and the rest..... oh yea, that and Freakachu stepped on Mario's hat.
Hope that helped!
PS: I think there are no Orange Yoshies because of the way video imaging works. There are 3 primary colors of video imaging (just like in art!) But they are slightly different: Red, Green, and Blue. Now, using these colors, it must be hard to make orange on a video screen, and take up more memory than the other colors. Now, why waste memory on an Orange Yoshi if any other color (green, yellow, blue, brown, white, etc.) would work just as good? This explains why there are no orange panels in Tetris Attack, or no orange ! blocks in SWM or SM64, and the list goes on. My opinion though.
*My real signature went on strike, said something about "unfair working conditions". So, this is a temporary replacement sig, until I can work things out with the real sig.
