Accordion Man

A character crushed by an Anvil On Head or other large object (e.g. piano) will often stumble away, being squashed into a pleated and flexing shape like an accordion, frequently accompanied by accordion music.

Compare to Squashed Flat.

And no, it's not a new and bizarre Robot Master.

Chester Cheetah of Cheetos fame got that way from falling into a sewer.

Video Games

Wario, when he gets slammed by a massive hammer, turns into one of these; it gives him super bouncing powers.
Space Quest, in the falling death pictures in the third and fifth episodes.

Western Animation

Happens to Monterey Jack in the third part of the Chip 'n Dale Rescue Rangers Five Episode Pilot "To the Rescue". When Fat Cat accidentally steps on him while running, he turns into an Accordion Mouse for a second before stumbling on along his way.
Happens to Peter in Family Guy when, true to form, a piano falls on him.
The Mickey Mouse cartoon The Cactus Kid (happens to Pegleg Pete, pictured at right) and others.
Frequented a lot of Tex Avery cartoons.
Several Tom and Jerry cartoons, one time in which the Italian dog that gave Tom that injury promptly proceeded to play Tom like an actual accordion.
And plenty of Looney Tunes shorts. A certain Coyote, Wile E. is occasionally subject to this, with appropriate sounds. On a couple of occasions, a crashing piano gives him piano keys for teeth which began spontaneously playing a song, instead of turning his body into an accordion.

It happened a couple of times in Rocko's Modern Life most notably after Rocko and Heffer crash into the ground on a cheaply made roller coaster.
It happened to Eddy in the Ed, Edd n Eddy episode "Tag, Yer Ed", after Lee Kanker slammed him head first into a wrestling mat. She then starts playing him like an actual accordion.
- Edd suffers a similar gag in "Laugh, Ed, Laugh", getting smacked into a street lamp while trying to subdue a scam-deprived Eddy. When Ed picks him up off the ground, he's scrunched flat and has a hilarious dazed look on his face.
An episode of Ka Blam! had Henry and June bring in the guy who invented it, but then his thank-you list was too long, so June sent down an anvil on him...and he performed the trope.
Happened to Lucius on Jimmy Two-Shoes.
The Jungle Book featured a variation of this: whenever Kaa gets his tail caught in some bamboo, when he frees it his tail flies back at him causing himself to recoil instantly (he is a snake), making an accordion noise as he does so.
