The eggs are pissed because their sole existence is to house a creature, letting the creature feast on its insides until the said creature hatches and kills the egg leaving yolk and shells everywhere. The entity that resides in their belly in turn releases more eggs, ultimately causing pain to the egg race in and endless cycle. Any further questions?
Sorry if this is a double comment, but on the quest "Artistic License 2" Unlock is spelled unolck. Not sure if it's that big of a deal, but I just thought I would point it out.
