When the top part of the tower broke off and fell, the power line that fed the glowing orb was also severed. The orb dimmed as it fell onto the deck of the frogman's flagship. Since no new fog was being produced anymore, the fog covering the frogman fleet slowly dissipated. The air above the lake became clear again.
Once that happened, the Allied fleet took a more active approach. They rushed in and made short work of the pirate fleet. Their ships were better, their firepower was stronger, and their number was more. Combined with John's excellent command of the fleet, the frogmen learned that they were in deep shit in no time. Even the Kraken was having trouble facing the fleet's combined fire.
The frogmen started to flee. Those who were on board the damaged ships even jumped into the water and fled by swimming.
