History Main / WhaleEgg

** In fact, egg-laying as an ancestral mammalian trait may have existed almost exclusively among Mesozoic mammals. In which case, there would be animals superficially looking nearly identical to badgers, otters, or possums...except they laid eggs. The otter-like ''Castorocauda'' is probably one such example.

* The plot of ''VideoGame/TheLegendOfZeldaLinksAwakening'' is to break the ostentatious egg of the Wind Fish, which is essentially a gigantic, telepathic whale with disproportionately tiny wings (Also to fight evil Kirby clones, but that's irrelevant at the moment). How the egg was actually laid by the (seemingly male) Wind Fish and why it [[spoiler:houses a mysterious labyrinth can both likely be explained by the whole adventure being AllJustADream. Specifically, the ''Wind Fish's'' dream, which Link is trapped in]].

** The question of how any particular mon couple mates and lays eggs is [[GRatedSex sidestepped]]. To breed two creatures, you leave them at "daycare" together; eventually one of the daycare-takers will give you an egg, saying that they "don't know where it came from, but your Pokémon had it." There's a trainer class of "Pokémon Breeders," but somehow no one in-universe seems to know how the eggs are produced. Considering [[HotSkittyOnWailordAction some of the Pokémon that can breed together]], [[BrainBleach this may be a good thing]]. ''Pokemon [=HeartGold=] And [=SoulSilver=]'' finally seem to address this issue in a scene involving Arceus at the Ruins of Alph: [[spoiler:every time a Pokémon egg comes into the world, it's literally because Arceus created it.]]
** And finally subverted by an NPC in Coumarine City: according to him,Pokémon eggs aren't really eggs at all, and instead are sort of like a "cradle" for newborn Pokémon to develop in until they're strong enough to survive in the world. This is also why a majority of them are BornAsAnAdult. That said, it brings up questions about how [[HotSkittyOnWailordAction different species can breed]] since some would logically lay eggs and others would give birth, but can reproduce together anyway.

** In "[[Recap/TheSimpsonsS12E17SimpsonSafari Simpson Safari]]", a baby Rhinoceros is seen breaking out of its egg. [[LampshadeHanging Lisa points out]] that rhinos [[DefiedTrope DON'T do that]]. [[EnforcedTrope Homer points out that they obviously DO]], since they just saw it happen.
** [[ThisIndexIsNotAnExample The scene the trope name comes from isn't an example]] as it's not an egg but an isolation chamber that [[TheDitz Ralph]] just ''thinks'' is an egg.

* ''WesternAnimation/{{Futurama}}'': Leela mentions that she occasionally lays an egg, [[JustifiedTrope more than likely, due to her mutant DNA]].

* A popular ''WesternAnimation/StevenUniverse'' AlternateUniverse, affectionately nicknamed "Gem Egg Hell", involves [[StarfishAliens Gems]] reproducing by laying eggs. Said eggs usually hatch into either clones of the parents or their [[FusionDance Fusion]].

Popular {{Mon}}s trope, as pretty much every Mons series uses it. Especially the ones that originate in video games, where it also serves to simplify the breeding mechanics -- see HotSkittyOnWailordAction. May also overlap with CosmicEgg, if the egg in question produces or is laid by a deity. Contrast with PregnantReptile, in which a non-mammal reproduces the mammal way.

* Happens as a (disturbing) twist at the end of the ''Literature/{{Goosebumps}}'' book ''Egg Monsters From Mars".

** Theres also Pakhyeokkeose, Seoktalhae and Kimalji, three founders of Silla Kingdom. Plus there's King Kim Suro, founder of Gaya (a minor kingdom that was later absorbed into Silla).

* In the ''Franchise/UltraSeries'', some kaijus, despite being hatched from eggs, have mamalian traits. Such as the elephant-like Sartan from ''Series/ReturnOfUltraman'' and the lion-based Gora from ''Series/UltramanEighty''.

* In ''VideoGame/{{Minecraft}}'', in creative mode, any and all of the mobs can be spawned with eggs, even pigmen and ghasts and ''villagers''.

* The plot of ''VideoGame/TheLegendOfZeldaLinksAwakening'' is to break the ostentatious egg of the Wind Fish, which is essentially a gigantic, telepathic whale with disproportionate wings! (Also to fight evil Kirby clones, but that's irrelevant at the moment.)

* ''VideoGame/{{Spore}}'': Every creature hatches from an egg, be it lizard-bug, or snake-monkey, or what have you.

* When Mary asks Max how babies are made in ''WesternAnimation/MartAndMax'' he says his mother told him that babies hatch from eggs layed by a rabbi.

* In ''Film/SuperMarioBros'', Daisy hatches from an egg. [[HumanAliens Despite appearances]], she's the child of a [[BeastMan dinosaur-person]] and the dinosaur-people are still oviparous.

* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "Luna Eclipsed", Pinkie Pie is dressed up as a chicken for Nightmare Night. At one point she get so spooked she lays an egg. A dragon egg. Somehow.
* ''WesternAnimation/{{Futurama}}'': Leela mentions that she occasionally lays an egg, more than likely, due to her mutant DNA.

** In "[[Recap/TheSimpsonsS12E17SimpsonSafari Simpson Safari]]", a baby Rhinoceros is seen breaking out of its egg. Lisa points out that rhinos ''don't'' do that. Homer points out that they obviously ''do'', since they just saw it happen.

* The ''Toys/Hatchimals'' line revolves solely around this trope. As such, all the animals, regardless of appearance, hatch from eggs. This even includes [[OurPixiesAreDifferent pixies]].
* ''Toys/Furby'': Furbies also hatch from eggs. Appearance wise, they're like if you [[MixAndMatchCritters crossed a koala with a penguin]].

** The game also gives this trait to pretty much any beast that has bird-like wings, no matter how much it resembles a mammal otherwise. Griffons, hippogriffs, and pegasi all hatch from eggs, although 5th edition describes pegasi as giving live birth instead. (It's mentioned in the description for avorials, or winged elves, that there's an in-universe belief that this is true for them, but it is not.)
