A Creator/{{Disney}} animated short released in 1952. It was conceived by Creator/BillPeet and is narrated by Sterling Holloway.

Lambert, a lion cub, is mistakenly delivered in a flock of sheep by a stork. He is taken in by an ewe after none of the delivered lambs choose her to be their mother. Lambert lives his life thinking he is a sheep until he is forced to unlock his true nature to defend the flock from an attack by a hungry wolf.

On a trivia note, the original print of the film was given as a gift to Emperor Hirohito of Japan because it was reportedly his [[GermansLoveDavidHasselhoff favorite Disney cartoon]].
!! This short provides examples of:

* AdultFear: Quite a bit in one short:
** Having your child taken away from you.
** Having your child bullied due to being adopted.
** Being viciously attacked in front of your child.
** Having your parent attacked in front of you and everyone (including yourself) being too afraid to help.
* AllOfTheOtherReindeer: The other sheep make fun of Lambert, until his size and lionish aggression save the day. Imitating the TropeNamer was a common theme in writer Bill Peet's work.
* BadassUnintentional: Lambert is unaware that he's a lion until the wolf forces him to unleash his inner lion.
* BerserkButton: Lambert works up the nerve to scare off the wolf when it threatens his mother.
-->'''Narrator:''' But when he saw the wolf approach\\
And heard his mother cryin'\\
Something ''snapped'' inside of him\\
He was a raging lion!
* BewareTheNiceOnes: Lambert is very gentle and "sheep"-like, but when he needs to defend his flock, he unleashes his inner lion.
* ButtMonkey: Lambert, initially. He is repeatedly mocked and humiliated by the sheep of the flock, even as an adult.
* CowardlyLion: Literally. Lambert is a scaredy cat and runs away at the first sign of danger. Until he realizes that he's a lion, that is.
* DeliveryStork: A delivery mistake sent Lambert the Lion to a sheep farm alongside other baby lambs. [[note]]Doubles as a cameo. This is the same stork that delivered Disney/{{Dumbo}}.[[/note]]
* DisneyVillainDeath: Subverted, surprisingly enough. Lambert apparently headbutts the wolf off a cliff and to his doom. The narrator reveals at the end that the Wolf's alive, stuck on a branch with berries for food. However...
* FateWorseThanDeath: The Wolf is a vicious predator now trapped with a tiny bit of fruit unable to move lest he die. The narrator also notes that the berries only grow there every spring.
* TheFourthWallWillNotProtectYou: The first-person perspective shots of the wolf coming to attack the sheep, which is StockFootage from Disney's version of ''Music/PeterAndTheWolf.''
* GentleGiant: Despite being a gigantic lion, Lambert is one of the sweetest creatures around.
-->'''Narrator''': "Isn't he HUGE?!"
* InterspeciesAdoption: Lambert is a lion who was raised by a sheep.
* KidsAreCruel: The other lambs are not at all kind to Lambert once they find out he cannot baa.
* LetsGetDangerous: Lambert is cowardly and sheepish, but once his mother is in danger he realizes what it means to be a lion and fights the wolf.
* MightyRoar: Lambert lets one out once he realizes he's a Lion.
* MamaBear: When The Stork tries to take Lambert back, his mother attacks the stork, causing him to back down and allow her to raise the lion as her own.
* MommasBoy: Lambert is very protective of his mother, and becomes the King of Beasts he is when he realizes that his mother is in danger.
* NurtureOverNature: Zig-zagged. At first, there is absolutely nothing predatory about Lambert, because he was raised as a sheep. However, when roused by a call for help from his mother, the only one who ever treated him kindly, he becomes a rampaging predator. But even in the midst of his roaring charge, with fangs bared and claws unsheathed, he still ends up attacking sheep-style - by ''headbutting'' the wolf.
* ObliviousAdoption: Lambert doesn't realize that he's not a sheep. Everyone else, however, does.
* OffscreenInertia: The Wolf is stuck on a branch on the cliff at the end. {{Lampshaded}} by the narrator.
* OhCrap: The Wolf once he realizes he's just ticked off a very angry MommasBoy.
* OnceUponATime
* ParentsInDistress: It's his adoptive mother being in danger that unlocks Lambert's true nature.
* RaisedByWolves: Or rather, sheep.
* RhymesOnADime: The narration and dialogue rhyme most of the time.
* RoleReprisal: Sterling Holloway, the voice of the DeliveryStork in Disney/{{Dumbo}}, reprises the role for the Stork's cameo appearance here.
* SavageWolves: The villain is a wolf trying to eat all the sheep.
* ShoutOut: The story is obviously inspired by an oft-paraphrased line from [[Literature/TheBible Isaiah 11:6]][[note]]"The wolf shall dwell with the lamb, and the leopard shall lie down with the young goat, and the calf and the lion and the fattened calf together; and a little child shall lead them."[[/note]], which is often quoted as "the lion and the lamb shall lay down togetherů"
* StockScream: The wolf bellows the Goofy Holler when Lambert headbutts him off the cliff.
* TookALevelInBadass: Lambert spends most of his time as a meek and harmless lion. During the climax, he unleashes his inner beast and fights off the Wolf.
* UseYourHead: Lambert headbutts the wolf into a cliff in the film's climax.
