Outrageous and Awesome are the other fairly nasty Special Zone levels. Funky has green Yoshi berries--the only level to do so. And the message in coins at the end. This is a conceit that may reference World 9-4 of The Lost Levels, which had a bunch of non underwater enemies marching at you as you swum above them, and then blocks spelling out a congrats in Japanese kanji. I'm sure whoever the psychopath who programmed the Lost Levels was very proud of Tubular, a freakish level when you're a kid...."WHAAAAAAA???"
Early demos of SMW had levels with "No Yoshi" signs which would force you off Yoshi if you tried to pass. This was removed from the game.
As a kid I didn't get how to beat the Vanilla Ghost House and just went the other way up through the west side (*flashes gang sign from 1994*) of Vanilla Dome, over Butter Bridge and down through to the Forest Of Illusion with its freaky trees. Ludwig in #4 with his sick grin, giant fireballs and freaky backflips scared the f. out of me. As an adult recently playing, I got LOST in the stupid Vanilla Fortress loop.
I never once got killed by the Koopa Kids in Mario 3. NEVER. You hear me, Twentyman?
Ugh, early 90s surfer dude speak. You chode!! You poser!! Suck a pipe, roadie!!
