Fogged eggs on a scroll
Fogging is an action that is done on an egg or unfrozen hatchling that is sick; fogging will prevent it from getting views and most of the time will cure it (see Dragon sickness for more information).
Only the owner can see the dragon's info page. If you do not own the dragon you will see the message "You can't seem to find the dragon you're looking for."
The image for a fogged dragon is the same image for the Glitch Dragon.
Sprite
Fogged egg or hatchling
When an egg is fogged it will temporarilly change the sprite so nobody can see it.
