- Onion (Calvin)
- Fat (Susie)
- Amino Acid (Russy White)
- Bread (unidentified, but briefly assumed by Hobbes in order to help Calvin rehearse)
Bread: "Glucose is the body's main energy source!"
Onion: "In addition to supplying vital nutrients, many vegetables are a source of dietary fiber."
The children probably stepped forward in turn, and recited what their character did in terms of nutrition.
Calvin is given the role of Onion in the play, and declares it a role that will have the audience in tears. However, Calvin struggles to learn his line, even with the help of Hobbes. Meanwhile, Calvin's mother is left with the task of creating an onion costume for Calvin to wear in the play, which turns out to be "Jabba the Hutt meets Rudolph the Reindeer," as Calvin puts it.
The Day of the Play
With just a few minutes before he's to go on stage, Calvin finds himself with a pressing need to go to the bathroom, and heads to do so. However, while he's there, his shirt ends up getting caught in the zipper of his costume, rendering him stuck in the onion suit. He tries to call for help, but no one answers. In a panic, realizing he's supposed to be on stage saying his line, he manages to yell his line perfectly.
When they realized Calvin missed his cue, the play was stopped and a janitor was sent to the bathroom to find Calvin. The janitor managed to free Calvin from the onion costume, but the damage had already been done and the play was ruined. Calvin tells this story to his mother, but he takes pride in the fact that he remembered his line.
This is the one and only scene when Calvin mentions a Star Wars character, "Jabba the Hutt."
