If the player gets hit by a morph ovum projectile, they will transform into a chicken, and will have only 30% of their health. They cannot go over that limit and are more vulnerable to enemies. There is an advantage to this state in that the small size allows the player to go under low ceiling areas which would otherwise not be reachable. While in the chicken state, the player has a very weak "pecking" attack and is unable to use any equipped weapons. The Morph Ovum is useless against Iron Liches, Maulotaurs, D'Sparil, and his Chaos Serpent.
