This is a baby chick, not a dragon. So what was it doing in the dragons’ cave?

This chicken is up to mischief. Ever since it discovered that it could copy the roar of an angry black dragon to perfection, it has taken a liking to playing pranks. Every Christmas it disguises itself as the egg of a Holly Dragon and heads out to a certain area of the cave, accompanied by growing crowd of interested spectators. The amused spectators are hiding in a nearby group of trees to watch the annual spectacle. As soon as an unsuspecting egg hunter arrives and hastily tries to grab the "Holly Egg", the chicken releases a surprisingly loud "ROAAAR". The faces of the startled hunters are priceless.
