The boss scales according to the number of players who enter. After using the lever, you immediately start fighting the boss.
At every x% of the boss's health, fires will spawn that need to be extinguished using a bucket of water.
The bucket of water will spawn somewhere in the room, so you need to find it quickly.
Around 6 or more fires will spawn. They explode every few seconds, covering several sqm tiles and dealing significant damage to both you and your Pokémon. During this time, the boss takes greatly reduced damage.
After extinguishing all the fires, the boss returns to its normal form. After losing another x% of its health, the fires will spawn again, and so on.
After defeating the boss, a bag should appear on the ground. You need to click it to receive your rewards.

This is what the fire that needs to be extinguished looks like:
