I made another biomorphic design. I put a frosted glass ball in the center of this one.
Oviparous animals typically have at hatching a toothlike structure ("small, sharp, cranial protuberance" cf. Wikipedia) which they use to tear or break out of the egg. Sort of a tiny LifeHammer. Such structures are seen in most birds and reptiles as well as monotremes, a few frogs, and some spiders. In birds the egg tooth is a horny growth on the upper beak, and the chick has a specially developed neck muscle with which to operate it.
