Crash Bandicoot - Complete 100% Walkthrough - All Gems, All Boxes, All Bonus Stages

As the title suggests, this is a full 100% walkthrough of Crash Bandicoot. I play through the entire game from start to finish without skipping anything, and I complete all the bonus stages on the way. This means I have to play many of the levels twice, but that's how a 100% run works. Another goal I set myself was to get all the boxes in the bonus stages as well, like you have to in the later games, but I encountered one box in the second Cortex stage that I simply could not get. You don't have to get any <br/><br/>
