Serves as scouts for the gnomes. If they spot you, expect to be mobbed once it runs off to tell its friends. The Flamingos in the northern section are an exception to this.
Flamingos in the south eastern section of the Greens tend to spawn and then form somewhat of a semi-circle, going off in different directions. This makes it hard to use ranged combat rings such as Fire Rain or Hornet's Nest.
