The episode starts with Richard, Gumball, Darwin, and Anais lounging on the sofa, watching television. They then notice Nicole staring at them sternly and try to decipher what she could be angry about, but to no avail. Nicole reveals that "a certain someone forgot a certain something." Gumball is confused, especially once Nicole is led to believe that the gang has planned a surprise for her special day and are playing dumb. However, after a series of potential surprises that turned out to be ill-timed coincidences, she becomes disenchanted in realizing that they truly did forget. The kids decide that they have to make it up to her.
