The Eggverse is like our Universe, but everything (like galaxies, stars, planets, buildings, objects, humans and even YOU!) are shaped as eggs. Everything is EGG-SHAPED here! There are also multiple eggverses in the Multiverse! Each with different laws of phisics (such as instead of everything being shaped as a chicken egg, it might also be shaped as an ostrich egg, quail egg and so on) so this makes it also a type of universe, they can be as small as an atom to as big as a bunch of universes put toghether!
Did you know that HowToBasic killed Eggverses during his videos? Well, it's also his favorite type of Universe!
