Egg MacGuffin

Go To

Number 9 Man: But — and this is the great secret of our age — we believe the Encyclopod left an egg behind.
Fry: Is it edible?
Number 9 Man: We're not gonna eat it! Not unless we find a second one.

Sometimes, an episode of a series may involve a character discovering an egg of some sort which later hatches. Occasionally, the protagonists may save the egg from a terrible fate: either from being smashed or from being something or someone's lunch. The egg eventually hatches and the character gains a Pet Baby Wild Animal.

Usually the baby is a Sidekick Creature Nuisance (though it may actually be a gargantuan creature with the mind of a small annoying one) that thinks the first person (usually the discoverer) it sees is its "mama". Usually, the baby may be far too much for the character to handle and they have to somehow find its real parents. A common variant has the egg hatching into something evil.

The trope can get even more unusual when the resulting offspring ends up taking on the characteristics of the hatcher, rather than who actually contributed to the genetics.

If the plot revolves around the unknown origin or result of a different kind of egg, it may be Who's Your Daddy?. Technically speaking, this is basically what happens in any mammalian or internally fertilised species, where legions of sperm race each other to get to the ovum.

A frequent cartoon scenario has a Talking Animal, or more often a Speech-Impaired Animal, is trying to keep an egg warm without being interrupted or losing the egg in a offbeat chase scene. When the egg hatches, this often results in the (usually male) babysitter being referred to as Mommy.

Compare Egg Sitting, where the egg is just a stand-in for a baby.

Despite the trope name, the egg itself does not necessarily need to be a MacGuffin. The trope's name is a silly pun on Egg McMuffin, the McDonald's breakfast sandwich.

  • In Digimon, digi-eggs are the beginning and end of a Digimon's life cycle, with a Digimon reverting to egg form after "death." (There are exceptions to this, such as season three, which began the trend of new seasons being AU and thus had different rules, and season five, in which rebirth was automatic again... making it all the more horrible when the villainous Kurata creates a means of corrupting a Digimon's data so it can't ever be reborn. Once, Seraphimon, a god/king to the season four version of the Digital World, had to be toted around by Bokomon, who had it strapped to his stomach and acted pregnant for well over ten episodes until Seraphimon hatched as Patamon. And then proceeds to refer to Bokomon as his "papa-mon". No reference or mention is made of the fact that Bokomon could, if he wanted to, become The Man Behind the Man ruling 1/3 of the digital world.

Its Insert Song is "Hello, Baby.".

Instead of the huge, horrible beast the characters feared, it hatches into a little blue penguin-y thing. Keiko dubs it "Puu" and it becomes her pet. Then in the next arc, Yusuke dies and reincarnates as a demon. Cue Puu growing into a huge demonic version of itself.
    • It is much different in the anime form - partway through, Yusuke finds out that his apartment has caught on fire due to his mom passing out with a lit cigarette. Keiko rushes in to save Yusuke's body, but is threatened with the flames. Yusuke is put in a Friend-or-Idol Decision and decides to use the egg save her. This turns out to be a Secret Test of Character and Koenma reveals that, oh yeah, the creature that hatched would have eaten your soul if hatched normally. Yusuke's selfless act, though, allows him to return to life.

  • Brood Parasites:
    • Some species of birds, such as cowbirds and a few cuckoo species, will lay eggs in other bird species' nests in order to "trick" the host mother into raising their offspring. Alternatively, the parasitic birds may go so far as destroying the host nest if the host ejects their egg, which often looks conspicuously different from the host's eggs.
    • A few species of fish and insects also practice brood parasitism.

How well does it match the trope?
