The egg you chose hatched into a demonic Crimson. Better feed it before it decides that you taste good.
Crimsons are truly bloody minded beasts, larger in size than Teals, but smaller than Golds, and are equally divided between male and female. They consider themselves the ruler unless there's a Gold or Charcoal around, and will do anything to prove that fact to lesser colors. Woe befall those who dare to carry two Crimsons around, for they will always be at one another's throat without mercy, until one is the proven victor.
