Jawbreaker is a toy in the M*A*S*H TV series, but it doesn't play a significant role in the storyline. It's a small running gag used for humor.
Here's what happens to Jawbreaker:
* It appears as a prized possession of Corporal Maxwell Q. Klinger: He often carries the toy with him, using it to express his frustration with the war and his desire to go home.
* Jawbreaker is frequently used as a comedic prop: Klinger uses the toy in various antics, like threatening to use it as a weapon or pretending it's a grenade.
* It's never explicitly mentioned what happens to Jawbreaker: The toy continues to appear in the series, sometimes being lost and found, but its ultimate fate is never revealed.
So, while Jawbreaker isn't a major plot point, it adds a bit of whimsy and humor to the series.
