Trailer Son and Mom

The Trailer Son and Mom are minor characters in Monsters, Inc.

Monsters, Inc.
Their only appearance in the movie is after Mike has Sulley throw Randall through the door to banish him to the human world.

Only their shadow is seen through the trailer window as the son calls to his mother that another "gator" got in the house. The mother then tells her son to give her a shovel, which she then uses to beat up Randall as her son cheers her on.

Trivia

 * The trailer makes a cameo in A Bug's Life in the background when Flik goes to the big city. However, no residents make an appearance.
 * A Pizza Planet delivery truck can be seen to the left of the trailer, just like in A Bug's Life.
 * According to the commentary, the "boy" is actually the model of the simulation kid wearing a cap and the "mom" is a bigger version of the said model with a "bun" placed on the head.
