Charlotte is stuck at the bottom of the ocean with concrete shoes. Vendetta and Rubella enjoy themselves by attacking the other children with fiends. At Vendetta's house, she is happy because of the successes she had with her fiends and considers Rubella a friend. Grudge sees them bonding and it saddens him. Later at school, Rubella gives Vendetta a teddybear that produces a happy tune for being her friend. Vendetta throws it away because of the music. Rubella picks it up again and the music keeps on playing. Vendetta falls to the ground and screams for help. Grudge sees this and eats the bear to stop the music. Relieved, Vendetta stands up again and yells at Rubella. She prepares to take Grudge home with him again, but then the greeting card and teddybear in his stomach start making music again. Angry, Vendetta tells both Rubella and Grudge to stay away from her.
Meanwhile, Charlotte stays alive because Buttons 2 threw a salad bowl in the ocean, making it sink and landing on Charlotte's head and providing her with air. She starts singing a song about the sea and her concrete shoes. She steps upon a big clam that takes her up to the surface, but a giant squid shows up and takes her.
