The episode begins on a sunny afternoon; Gumball is just about to eat a hot dog for lunch, but he notices something wrong: he is without his favorite sauce, ketchup! Immediately, he leaves the house to buy some more ketchup at the mall. On his way to the mall, he begins to rap about how he just loves ketchup; however, his intense rapping distracts him, and he ends up bumping into his former friend, Hot Dog Guy, and causes him to drop his phone. This leads to an awkward reunion between the two that results in them "becoming in sync." Quickly, the two try to get away from each other; when that fails miserably, the two just accept that they will have to ride the same bus together.
