Castle Machinery

Watch out!Doctor Nitrus Brio isn't far and and an evil crate bridge try to stop your quest of the gem,be fast and escape to the castle machinery

Castle Machinery is the twenty-fifth level in Crash Bandicoot. It is right before the boss fight against Doctor Nitrus Brio. If you have obtained the green Gem in the game, a secret platform appears right next to where the level begins. This platform takes you up to a secret part of the level that has a lot of extra lives preparing you for the forthcoming challenges. There is then another platform there that takes you to the end of the level. Oddly, this is the only level in the game with a secret Gem route with crates only in the main route.
