Volumetric Mouth

"Drawing Calvin is easy! You just make a big mouth and add some hair!"
Hobbes, Calvin and Hobbes

Mouths. Some can be big, some can be small. And then there are these.

This trope is for when a character shouts so loud, their mouth takes up the entirety of their face, presumably to imitate the effect of a Skyward Scream. A variant exists in which the mouth is viewed from the side.

This is usually used in print and animation.

Sometimes, mouth size and volume are related (i.e. a character speaking softly is indicated by a small mouth).

A character with No Indoor Voice often talks like this. Often coupled with Suddenly Shouting, Big "NO!", Big "YES!" or Say My Name. Compare Demon Head, in which the entire head expands.


Comic Books
  • The Smurfs are sometimes drawn with these type of mouths.



Newspaper Comics

  • Shown by a guy on the playfield of Earthshaker!, as he's being sprayed by a fire hydrant.
  • The Loopy Martians in Big Bang Bar are modeled like this, in order to hold locked pinballs in their mouths.

Video Games
  • Pokémon uses this with Zubat's and Golbat's sprites, to convey screeching.
  • Rhythm Heaven: The choir boys from Glee Club.
  • In the 2D Sonic the Hedgehog games, Sonic does this if one dies by drowning. The same sprite is used when you die from anything in Sonic Spinball.
    • In Sonic Adventure, Sonic's mouth stretches out in uncanny ways when he says, "You're gonna crash! AAAAAAH!" and, "WHOA! A Chaos Emerald!" Even more so in the Dreamcast version.
  • From Jet Set Radio, we give you Professor K.
  • Baby Mario in Yoshi's Island, whenever he's stuck in the bubble and crying.
  • Several GMod videos do this.
  • In Rayman Origins, whenever the characters get injured, their mouths will be huge. This even happens in the intro, when Rayman realizes he is holding the old man skeleton's skull in his hand, and he (as well as everyone else) start screaming. "WAAAAAAAAAAAAAAAAAAAAAAAAAAAA!"

Web Animation
  • Egoraptor is known for this.
  • Strong Bad describes what he would look like as a Japanese cartoon character:
    "Then there's my mouth. Real tiny when it's closed; ridiculously huge when it's open."


  • SCP-096's mouth is 4 times the size of a regular human's mouth... & looking at it will result in you getting killed by the creature that its attached to.
