In cartoons, characters will sometimes change into something that symbolizes or is associated with the situation at hand. Common versions of this include:
- A lollipop emblazoned with the word "Sucker" (the character has just been tricked).
- A donkey, with optional braying (the character is stupid or being a (jack)ass). In cases where actually saying the word "ass" would provoke the censors, this can double as Getting Crap Past the Radar.
- A shoe heel (this example is often aligned with guilt and remorse akin to the trope My God, What Have I Done? rather than being embarrassed).
- A dumbbell (a more direct Visual Pun indication of stupidity).
- A wolf, complete with Wolf Whistle (the character is lustful).
- A Smelly Skunk (representing that the character is about to do something heinous).
- In Spanish-speaking media, a character with a cheating partner gets horns. This comes from the idioms "ponerle los cachos" ("put the horns on her/him/them") and "cornudo/a" ("horned/cuckold").
- In Japanese media, a character "turning into a tengu" (i.e. acting arrogant or boastful) will grow a tengu's long nose.
- An angel, or gaining typical angelic attributes like a Holy Halo, Symbolic Wings, or illumination by Rays from Heaven. This indicates their innocence, virtue, or good nature. In contrast...
- A devil, or gaining typical demonic attributes like Horns, a tail, or devilish red skin. This indicates their guilt, villainy, or evil nature. See Scary Symbolic Shapeshifting.
Because Tropes Are Flexible, this, of course, can be done in media other than animation. Any visual format can easily make use of this trope. Figurative speech such as similes and metaphors in written media serves the same function, if usually more frequent and at the same time done in a subtler manner.
Likewise, metaphoric transformations can and have been used for purposes other than comedy such as in Furry Lens (a character is drawn as an anthropomorphic animal, but is considered human in-universe).
The transformed character will almost always revert to their original form. If they realize they've been permanently transformed, you can expect an Oh, Crap! moment.
In any case, this trope often runs on Stock Visual Metaphors.
Supertrope to Scary Symbolic Shapeshifting, when someone is briefly shown morphing into a scary or disgusting form to show to the audience how loathsome they are. A specific form of Visual Pun (a play on words in the form of an image). Contrast Literal Metaphor (a character makes a figure of speech and they—sometimes sarcastically—say that they meant it literally). Compare Narrative Shapeshifting (a character shapeshifts while trying to describe something). Related to Shameful Shrinking (a character literally shrinks down due to embarrassment and shame) and Buzzsaw Jaw (eating so fast that your mouth turns into a buzz).
Examples:
