Below is the code from The Artemis Fowl Files decoded into English. The code is originally written in Gnommish.
When a fairy is trapped above ground without magic it is best to avoid contact with humans. Hide in the shallows of a river as humans, especially children, do not like to wash themselves. drape yourself with the skin of a sheep or goat as humans are often not clever enough to notice.
If you are cornered by a human slap the ground with the flat of your hand as this will often frighten the mud men away.
If this is unsuccessful, admit that you are a fairy and humans, being cynical creatures, will think that you are a friend in a costume trying to make a fool of them.
If all this fails then ask the human if you could possibly borrow some money and the mud man will flee with great seed and never seek you out again.
