SpongeBob proudly presents his latest creation, the 'Rainbowger,' a burger containing all the colors of the rainbow, which he believes will bring the world together.

Plankton, observing SpongeBob's colorful creation, decides to use his color nullifier to remove all the color from the Rainbowger and everything else.

Plankton's color nullifier malfunctions, taking in too many colors at once, causing chaos as colors are removed and re-added randomly to the environment and characters.

Despite Plankton's efforts, the nullifier inadvertently makes everything more vibrant. Squidward even jokes about being a 'coloring book' as he is covered in hues, and SpongeBob credits Plankton with a 'publicity stunt'.

SpongeBob compliments Squidward on his newfound colorful appearance, to which Squidward responds with a characteristic dry wit, stating that his colorful exterior is merely superficial.
