I have never already been found many many metres under the earth dug, however, something. Pretty rare to find in the deep caves where Miru resists. Thanks for the question, Kartofl! Iron is found in the lower caves, below the ones just below the surface. Specifically, try looking around caves where there are a lot of stalactites.
YES. However, you will need to cook any dead lobster within 8 hours of discovering a lobster died. Remove the rubber bands from the claws of the dead (or suspected dead) lobster or cook it in a separate pot to distinguish it from the live lobsters.
It will die before the water boils. When the water has reached boiling point, lower the heat and simmer the lobster for around 15 minutes for the first 450g. Simmer for a further 10 minutes for each extra 450g, up to a maximum of 40 minutes. When the lobster is cooked, its shell will turn a deep brick red. Drain off the water and leave to cool.
