User blog comment:BonesMcGee/Brainstorm: Potential savings in using the hurry hatch trick/@comment-5434383-20120913213536

14 Sep: 48 attempts gave Dimetrodon (again?! Why do I get so many of these?)

84 more attempts gave a Giant Turtle (hatching now).

Just so I'm clear about some comments below, if you hatch any 12HH egg the 'counter' between 10 HH eggs DOESN'T reset? I had assumed that any hatching would reset the count, but maybe not?
