You're all a bunch of pigs! Dirty, rotten pigs!

— Sammy in his debut.

Sammy is a dead rat that belongs to Miss Mush. He ate her Mushroom Surprise which caused him to be dead. Despite that, however, he is perfectly capable of speech and movement, as seen when he wanders into class in a bundle of raincoats in his introduction chapter, and leaves rude comments about all of the students.


Sammy is a gray, dead rat. In his debut, he wears several stinky, dirty raincoats into the classroom. Underneath all of them, he hides, leaving crude comments about the other students.


While bundled in raincoats, Sammy acts awfully rude towards the other students, leaving mean-spirited comments about them. However, without the raincoats, Sammy doesn't seem to do much, appearing as an ordinary dead rat. However, Sammy's mere prescence can cause people to say the thoughts at the back of their minds, so Sammy still seems to have some sort of ability without his disguise.

Major roles

  • In Sideways Stories from Wayside School, a chapter called "Sammy" has him wander into Mrs. Jewls' class wearing several raincoats, only for Mrs. Jewls to take them all off. At the end, she discovers he is really a dead rat, scaring Mrs. Jewls, and having him be thrown into the garbage.
  • In "The Rat Truth", Miss Mush claims Sammy is sick (although he is dead), so she goes away to find the Golden Bowl of Mamaland to cure him. While she's gone, Sammy ends up being passed around, letting people say what they've always wanted to say while he's in their hands.


  • While in the books he is perfectly capable of speech and movement, in the cartoon he seems more like an ordinary dead rat, hardly doing anything at all.
