However, when Bolin, the Beifongs,and Zhu Li fly off on Juicy, the top of the cannon becomes visible again and all of the damage that happened during the fight has disappeared and the cart that was thrown has reappeared on the platform. Along with this, the rocks that the Beifongs used to tip the cannon earlier disappear.
