Pick up the key and prepare to leave. As you do, another quake happens which breaks the cages holding the Gadon. Now that the Gadon are free, they will start roaming the cave. The path that you took earlier has been sealed, so you will need to find another way.

Make sure to stay undetected by the Gadon as they are fast swimmers and once you’re caught, you will have to start over. They cannot be hurt by any of your weapons. They can see about a fair distance and they have a set patrol path, so try to find some nooks that you can hide in. Also, there are statues that you can hide behind which allows you to stay hidden even if they swim past.
