No not fluffy penquins

The photo is not a group of young penguins but a group of vacated eggs of the Green Shield Bug.

My question is how do the bugs exit their eggs?

Are the young enveloped in a sac with the black mask on its head. Inspection with a 10x lens revealed the mask is atop a tangled skin.
The mask is sharply pointed and the eggs cut precisely in a circle around the egg suggesting it is a kind of egg tooth swiveled round by the bug to cause the exit incision.

Are these assumptions correct? If not I would be please to hear the true story.
