Breed ID:

Sprites and descriptions
Alpha: This huge egg's shell is slick and incredibly tough.

Beta: This baby snakelike creature is very big, and grows quickly. It seems to like you, but tries to eat anything else it comes across.

Delta: This young snakelike creature is very big, and grows quickly. It seems to like you, but tries to eat anything else it comes across. It is getting too large to support itself on land, and now spends all of its time in the water.

Omega: Ceti (Cetus singular) are one of the largest creatures Gencorp's scientists have engineered. While loyal to humans, especially to the ones who raised them, and their mates and children, these enormous omnivores will eat anything else that moves and even things that don't, making them a danger to anything non-human they can't breed with. They are intelligent enough to easily train, and can safely carry large groups of people across water when fully grown.
