** ''Anime/DoraemonNobitasDinosaur'' have Nobita unexpectedly becoming the owner of the titular dinosaur, Piisuke (a ''futubasaurus'' that hatches from a fossilized egg restored by the Time Cloth). As a baby Piisuke can fit in a plastic beach bucket and shows up in a few scenes as a HeadPet on Nobita, but as it grows it becomes large enough for Nobita, Doraemon and all their friends to ride on. Naturally Doraemon have to use the [[ShrinkRay Shrink Light]] for Piisuke to fit in a container for the gang to deliver back to Japan.

TruthInTelevision when it comes to dinosaurs, as even the largest of the long-necked herbivores were no bigger than puppies upon hatching (though they did grow ''very'' quickly). The square-cube law is to blame since bigger eggs need thicker shells to support themselves but can't be too thick otherwise it prevents respiration for the growing embryo or is too difficult to break when its time to finally hatch.

* Amal from ''WesternAnimation/Primal'' is the size of a normal human child, but her father Kamau is a towering giant over nine feet tall: the same of which applies to the rest of their tribe. This also applies to Fang, a T. rex, and her far tinier babies.

** In the 2014 Legendary film, the female MUTO is as tall as a building, but she lays eggs the size of small cars, which relatively speaking are incredibly tiny.

* The baby ''Tyrannosaurus'' from ''Jurassic Park: The Lost World'' is small enough to be carried by one person, as opposed to its [[PapaWolf much bigger and angrier dad.]]

** ''Anime/DoraemonNobitasNewDinosaur'' have Nobita becoming the owner of a pair of dinosaur ''twins'', both of them hatching out of a single egg and can be carried by Nobita oj each hand. When growing up (reaching the dinosaur equivalent of adolscence within the span of a month) they're at least thrice larger than Nobita.

* ''Anime/DoraemonNobitaAndTheBirthOfJapan'' have Nobita using Doraemon's Life Creation Set to create any new "pets" he wants, so he mixes the set's DNA around and creates a Pegasus, a Gryphon and an Oriental Dragon. In their default forms, the trio are small enough to fit inside Nobita's clothing, but as adults (in a few weeks!) they can be rode on as steeds.

* The [[http://avatar.wikia.com/wiki/Saber-tooth_moose_lion sabre-toothed moose lion]] from ''WesternAnimation/AvatarTheLastAirbender'', which starts life as a rather cute Yorkie-sized cub and grows into a hefty 10' predator.
* Invoked example: An episode of ''WesternAnimation/DangerMouse'' has Baron Greenback get hold of a formula that made giant chickens. The eggs they laid, however, are normal size, and his plan was to distribute them to the world's doorsteps, so that when they hatch...

* [[http://godzilla.wikia.com/wiki/Godzooky Godzooky]] from ''WesternAnimation/TheGodzillaPowerHour'' is roughly human-sized. But he's less than half the size of his uncle Godzilla's ''head''.
* In ''WesternAnimation/KipoAndTheAgeOfWonderbeasts'' Mandu is a mutant piglet roughly the size of a housecat or a small dog, but later on we see some [[AttackOfTheFiftyFootWhatever Mega-Mute]] pigs that look like elephant-sized versions of Mandu with tusks. [[spoiler: After the timeskip in the finale Mandu has grown to her full size and is confirmed to be the same species.]]
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': Seems to be the case for dragons, generally.

Often used to incorporate the ShoulderSizedDragon trope in stories about much larger dragons. May be combined with CubCuesProtectiveParent. Contrast SmallParentHugeChild.

* ''WesternAnimation/IceAge3DawnOfTheDinosaurs'': The baby tyrannosaurs are around Sid's size, but the mother is taller than Manny.

** Two different snail-like monsters, Taraban from ''Series/UltramanTiga'' and Arandos from ''Series/UltramanCosmos'', have babies the size of train carriages (although the former can enlarge at will if needed), while the mothers are eoither the same size as the Ultras or even larger.
** The insectoid monster, Insectas [[ExactlyWhatItSaysOnTheTin (creative name, we know)]] has larva small enough to fit in a person's ear, while the adults are some 45 meters tall. The larva can grow to adult-size within a short period of time if it receives enough nutrients.

* In ''LightNovel/SoImASpiderSoWhat'' newborn Taratects are the size of a pig while the Taratect Queens that spawn them are [[{{Kaijuu}} bigger than dragons]].
