It is a black chalkboard and is bordered by wood. On the top of the board, "Good Noodles" is written in white chalk. Below that, the chalkboard is divided up into seven sections. Gold stars are awarded when a student does a good deed. However, when students cause trouble, gold stars are taken away from them.
Role in series
"New Student Starfish"
SpongeBob shows Patrick the board and explains its function before class starts. During class, Mrs. Puff threatens to remove a star from SpongeBob's section several times when he disrupts class, and finally removes one after SpongeBob is blamed for the "Big Fat Meanie" incident.
At the end of the episode, SpongeBob and Patrick are each awarded one gold star for saving Roger.
The Yellow Avenger
It reappears in Mrs. Puff's Boating School. At a certain point in the game, the player is given a task of grabbing some of the stars off the board to prove to Officer Nancy that SpongeBob is a good noodle.
Mr. Krabs and Plankton learn about the board from SpongeBob. They have a competition with each other to see who can earn the most stars. This consists of them both giving Mrs. Puff tons of fruit until she snaps and declares that none of them, including SpongeBob, will get any stars.
SpongeBob has the most stars in his class, with 74 total (73 after the "Big Fat Meanie" incident, but 74 again after saving Roger at the end). However, in "Teacher's Pests," he has zero stars.
The names on the board are SpongeBob, Lloyd, Sheila, Paco, Debbie, and Horace. Later in the episode, the name Patrick appears after SpongeBob adds it.
