Crash Twinsanity 100% Run - Madame Amberly

Another boss fight. You don't have to run around, just follow my tactic and you can't go wrong. The bell part is tricky but manageable.
I forgot to record the yellow gem. At the end of the video, there's the world crate. Just turn left and go to the edge of the roof. There should be a trigger crate. Jump on it and it will blow up the nitros in the air. Go down and hit the ! box with a ball and take the moving platform. Then simply jump on the iron platforms and you get it.
