Only the stinkiest of all the birbs. Often times is confused and wishes it wasn't so simple. However, because of it's stinky nature it will never be able to change. It's hard to define a simple birb but when you meet one you'll know...
Person 1: "Henlo friend where the seeds?"
Person 2: "You are such a simple birb, sensitive and stinky too."
