Yeah, I found the thing with the turtles too. The idea of that was given to me by Block, who had the idea of trying to kick the turtles to the end of part 1 of FC! And then I noticed that you could first get your hands back on, use the turtles to jump back upon the bridge and score more points than you'd be able to otherwise.
About the Razoff glitch: Someone on RZ reported it once I think, and then I tried it too and it happened to me a couple of times too, but I'm pretty sure I didn't invent that one. Also, I didn't find the thing in DOTK part 7 that you could make the cage give you a green gem instead of the Vortex. That was found quite early, before I became a better player. And I remember that we were all quite enthousiastic when we heard about someone getting 100k in SBTC because he found a way to get infinite points in the snowboarding part. But when I tried a LOT of times to earn lots of points with it first (and it took over an hour each time to restart the part!!!) and then tried to get the green gem, only to find it was a horrible way to play, I settled for 101600 eventually, and later when I decided to take another look at the level, I gradually found out better ways to score in part 2 of SBTC so that you didn't need the snowboarding trick anymore, which was also quite revolutionary. And I have to give MandM81 credit for perfecting two of the combos in that part (the one near the circular arena and the one with the snowman, the Hoodboom, the balloons, Hoodlums and Matuvu). And I believe I also managed to trigger that launching glitch near the green gem once, which gave me the idea to combo the green gem for 7500... just too bad I didn't manage it myself so far, lol. I also came up with the huge combo in part 3 of TBOM I believe, and also the green gem one if I'm correct. And the 3-matuvu combo was also my idea, I thought of it ever since I found out that you could get one of the Matuvus in the first room, from the last room! But MandM has beaten me on that one so far
If I haven't given anyone credit he/she deserves, just call me and I'll rectify it
Edit: I missed the last page, lol. I'm not 100% sure, but I think it was also me who found out how to get past the Knaaren. I did a lot of investigation on where the spot was to stand so he would come near you without hitting you away, and walking into him would cause you to break through. Yeah, I'm pretty sure I found about that too.
