The middle head is the oldest sibling, and the leader. The main personality of the middle head is being narcissistic and sarcastic. The back head is the youngest, and the logical thinker. He/she is mostly shy and socially awkward. The front head is the middle child, and the main talker. The middle child is mainly extroverted and humourous. All the heads must help the Doublgaggle survive. The middle head keeps things in check, the back head strategizes and makes plans, and the front head hunts and gathers food. However, if the heads do not get along well, the Doublgaggle might not make it long enough to reproduce, and will die.
