->'''Greaper''': He's sleeping.\\
'''Dry Bones''': Boy, he sure is.\\
'''The Big Boo''': Check those bubbles coming out of his nose!
-->-- '''The 3 Musty Fears''', ''[[VideoGame/SuperMarioRPG Super Mario RPG: Legend of the Seven Stars]]''

Particular to Anime: When sleeping, a character whose primary thrust is comedic develops a bubble of snot from one nostril that inflates and deflates in sync with their breathing or their snoring, especially if the character chooses to fall asleep during a very inappropriate time. Basically the anime equivalent of the '[[CatchingSomeZs Zzz]]' used in Western cartoons and comics. While usually considered a [[{{Squick}} pretty gross concept]] in the West, Japanese media tends to portray it as cute.

The bubble bursts upon awakening. In some cases, it is shown that you can awaken the character by popping it.

See also CatchingSomeZs for more universal version of sleep representation.
