Is that my voice?! (coughs) is that... MY voice?!!! Oh, well...
- Barbie movies:
- In Barbie in the Nutcracker, the Nutcracker himself used to be the rightful prince usurped by the Mouse King.
- In Barbie of Swan Lake, Rothbart has changed all the inhabitants of the Enchanted Forest into animals, and when Odette enters the picture, he makes her into a swan. In the epilogue, he gets his comeuppance by becoming a cuckoo-clock.
- In Barbie and the Magic of Pegasus, the titular pegasus used to be Princess Brietta, and later we learn that Wenlock's trio of miserable troll servants used to be his wives.
- In Barbie in a Mermaid Tale 2, the big bad, Eris, is given legs instead of a mermaid tail — her worst nightmare.
- Disney uses this a lot.
- Aladdin:
- The Genie turns Abu into a slew of things while hunting for a suitable "mode of transportation" for Prince Ali, ending with Abu as an elephant.
- Later, Jafar turns Rajah into a tiger cub and Abu into a wind-up monkey toy.
- Alice in Wonderland: Alice changes size at alarming rates. While it does happen because she herself consumes various food and drinks, she usually is unaware of the exact effects of the consumption.

- In Cinderella, the mice and dog are turned into the footman and horses. Cinderella III: A Twist in Time has the Stepmother steal the Fary Godmother's wand and ultimately turn Anastasia into a copy of Cinderella to steal the Prince away. While Anastasia might have been bullied into agreeing, she still seems rather upset about the whole thing.
- The Emperor's New Groove: features a slew of polymorphing potions going awry, and some of the results are much less than useful — a turtle, a parrot, a humpback whale . . .
- The main character, Kuzco, is turned into a llama by Yzma by means of one of these potions.
- And then there's the entire palace guard, who get transformed into several different creatures, though their baleful-ness is apparently up to the individual:
Guard: Uh... I've been turned into a cow... can I go home?
Yzma: You're excused. Anyone else?
The rest of the troops: Nah, we're good!- And of course Yzma gets her comeuppance when one of the final potions is used on her. And she turns into a fluffy little kitten. Cue Kuzco taunting her until he gets scratched.
- In The Little Mermaid, various merpeople are changed by Ursula into shriveled polyps.

- Kubo and the Two Strings:
- What actually ended up happening to Kubo's father, as a result of his relationship with Kubo's mother making her turn against her family. As we can see from the paper recreation, it looked very painful.
- In a way, the Moon King is also subjected to this, having been turned into a normal human by Kubo, something that he clearly would not have ever desired had he not lost his memory in the process.
- In Master Moley By Royal Invitation, the pilot film to The Misadventures Of Master Moley, when Master Moley and his friends perform the "Snuffle Shuffle" to get the attention of the Queen and her guests at Windsor Castle, they end up turning everyone, including the Queen herself, into moles.
- Edmund from Rock-A-Doodle is transformed into a kitten by the evil Duke of Owls, and upon realizing that he's been tranformed, he cries out "Jeepers, I'm all furry!"

- The Lake Witch turns trespassers into small fish which bite the skin off of her and her fellow mermaids' feet when they are in their human form. One of the fish is seen begging for help. Hansel is temporarily turned into one before the Lake Witch's daughter realises that Gretel is the agent who rescued her at the beginning of the movie.
- In Sheep & Wolves, Grey turns into a sheep after he goes to Mami the gypsy rabbit for help and she gives him a potion so he can "change", setting the plot in motion.

Later in the movie, Yubaba's giant infant son is turned into a mouse, and a large bird with Yubaba's head is turned into a tiny black hummingbird-thing. This trope is used a lot in Miyazaki movies, it seems.
- In Suzume, the cat god Daijin transforms Souta into a child's chair, though he can still walk and talk. Daijin did this both because he wanted to keep Suzume to himself and to force his role as Keystone onto Souta.

- Uberta in the second movie is transformed into several different animals by Sir Clavius to shut her up. It doesn't work.
