A type of transformation in which, most likely due to a curse, spell or potion, portions of your body start to turn into that of a creature until the whole body is changed. The order can vary depending on what animal or on the work. Often happens to a BalefulPolymorph.

* The picture image comes from ''Disney/{{Pinocchio}}'', in which bad boys turn into donkeys in this manner. The ears change first, followed by the tail sprouting from the back. This is followed by the head, arms and legs changing before the final stage of losing their ability to speak.
* ''WesternAnimation/PinocchioAndTheEmperorOfTheNight'' has the [[NightmareFuel infamous]] scene where Pinocchio is turned back into a puppet with different parts of his body become lifeless wood. Thankfully for little children, this scene had to be trimmed or cut from most TV airings.
* Possibly a ShoutOut to the above, Kuzco's transformation into a llama in ''Disney/TheEmperorsNewGroove''. The ears change first, then his neck changes, followed by his right hand, face and left hand. We don't see anything below the waist however.
** It carried on into ''WesternAnimation/TheEmperorsNewSchool'', where this would usually happen to anyone who sampled Ysma's potions.
* ''Disney/BeautyAndTheBeast'': Happens at the end when the Beast returns to his human form. The hands change first, then the feet change, and his head changes too. We aren't shown anything else, though. ''The Enchanted Christmas'' shows a flashback showing the prince's transformation into a beast, where the only part that's completely shown are his hands.
* In ''WesternAnimation/TheCurseOfTheWereRabbit'', this happens to [[spoiler:Wallace]].
* In ''WesternAnimation/BartokTheMagnificent'', Ludmilla drinks a potion that amplifies your inner self ten times and [[spoiler:slowly transforms into a dragon.]]

* Happens a lot in FanArt with characters both original and existing.

* ''Literature/TheAdventuresOfPinocchio'' and most film/TV adaptations have this where Pinocchio and the other boys turn into donkeys, usually with the ears first.
* Although using a shorter time frame than most examples, shapeshifting in ''Literature/{{Animorphs}}'' works this way. For added [[SarcasmMode fun]], the process is randomized every time. With practice, they can exercise some control over which part turns into what first (Jake manages to start a wolf morph just enough to change his throat to change his voice, Cassie impresses the Andalite sharing her brain by making Hork-Bajir arm blades appear in sequence). Turned into an artform by Andalites (who call it morphdancing).
* ''Literature/GooseBumps'': The book called ''Chicken, Chicken'' where two kids slowly transform into chickens over a long period.

* Happens to [[spoiler:Scrappy when changing into giant form]] in the first live action ''Film/ScoobyDoo'' movie. One of the few to deal with ill-proportioned transformations.
* This happens to [[spoiler:Sex Machine]] in ''Film/FromDuskTillDawn'' after he's [[ZombieInfectee bit by a vampire]]. First his teeth start changing, then his hands...

* Godai initially transforms into Kuuga this way, until he figures out his henshin pose, in ''Series/KamenRiderKuuga''.
* In the ''Series/ThatsSoRaven'' Halloween special, "Don't Have a Cow", Raven and Chelsea perform a spell that accidentally starts turning them into cows which continues as the episode goes on. They get (In order) cow ears, tails, snouts, hooves, and tongues. They also act more like cows as it goes on in which they eat and moo frequently. During the costume contest announcement the rest of the parts come and they are completely transformed [[spoiler:until it's revealed that it was all a vision]].
* ''Series/BuffyTheVampireSlayer'' - in "The Dark Age", Jenny Calendar is possessed by the demon Eyghon. At first the transformation is just in her attitude, becoming sexually forward (which an off-his-game Giles attributes to an earlier head injury), but quickly turns scornful, then growly-voiced with some forehead distortion. When she later returns, she's in full-on pointy-ear, big-forehead glowy-eyes mode.
* In an episode of ''Series/TheOuterLimits1995'', a human has been captured by aliens. He meets another captive, who is being subjected to numerous surgeries to gradually change her body into that of the aliens. [[spoiler:Turns out she was actually an alien spy being reverted out of her human disguise, [[CruelTwistEnding all the while playing on his sympathies to gain information]].]]
* Ang Lihim ni Annasandra, a Filipino fantasy TV series (fantaserye), has this when Annasandra turns into a boar and back.

* In the Music/{{Radiohead}} music video for the song "There There", Thom Yorke's transformation into a tree starts with his left foot, and progresses through his right foot, legs, torso, and arms. His face, [[AndIMustScream still frozen in a scream at the end of the video]], changes offscreen.
* Music/OzzyOsbourne's "Shot in the Dark" music video focuses on one female fan, who goes to an Ozzy concert and has a good time... until she notices her fingernails have turned black. Her panic increases as more features are altered. The end of the video shows her on a billboard (advertising the concert) as its lone character.

* ''VideoGame/LegoDimensions'': In the Creator/MidwayGames-themed "Retro Wreckage" level, Gamer Kid becomes a ''VideoGame/{{Rampage}}''-esque gorilla (and later, reverts back to a human minifigure) a piece or two at a time.

* In ''WebVideo/TheCartoonMan'', Roy transforms into a humanoid cartoon character bit by bit, beginning with his gloves, then his hair, and finally his eyes.

* ''WesternAnimation/AmericanDragonJakeLong'': In a variation of this trope, Jake and Hayley can willingly change certain body parts into that of a dragon's for whatever situation.
* ''WesternAnimation/TheLifeAndTimesOfJuniperLee'': In "Oh Brother, What Art Thou", Ray-Ray becomes a dragon this way. First, his hands and feet enlarge, followed by a tail growing. We don't see anymore after that and he's a full dragon the next time we see him.
* Happens in ''WesternAnimation/TurboTeen'' whenever Brett turns into a car and back.
* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'':
** The episode "Sickly Sweet" has Grim put a spell on Mandy that would cause her to gradually turn into a donkey/dragon hybrid when she acted mean.
** "Grim for a Day" has Grim and Billy turn into each other this way.
* In the ''WesternAnimation/LooneyTunes'' short ''WesternAnimation/YankeeDoodIt'', whenever the Shoemaker says the word "Jehoshaphat", the elf gradually transforms into a mouse (which can be undone by saying the word "Rumpelstiltskin"). First he gains a mouse's tail, then mouse ears, and finally into a full mouse. At the end of the cartoon, when the elf king visits the Shoemaker to check on his business, the shoemaker decares his next line of shoes to be named "the Jehoshaphat Boots", and the King goes straight into the complete mouse form.
* In a first season episode of ''WesternAnimation/JackieChanAdventures'', Jackie suffers bit-by-bit petrification over the course of the episode.
* In ''WesternAnimation/AdventureTime'', Simon Petrikov's initial transformation into the Ice King occurred very gradually. In the episode "Betty", [[spoiler:the Ice King temporarily became Simon for short period of time]].
* In the ''WesternAnimation/SabrinaTheAnimatedSeries'' episode "Board and Sorcery", Harvey turns into a snowman this way. His nose becomes a carrot, then his arms become twigs, before he's a full snowman in a flash.
