Becoming concerned about Beth who seemed sad on the phone the previous night, Momoko and her friends travel to New York City to investigate. Momoko learns that Beth has been overwhelmed with anxiety because she seems to have lost a special pendant that Sachiko's grandmother gave her during Thanksgiving. Sachiko joins Beth for lunch at school, wearing an identical pendant and asks Beth where hers is. Beth lies that she left it at home for safekeeping. Sachiko suggests Beth wear hers for the upcoming Christmas Party so they can match.
After school Beth softly cries to her teddy bear Collin (who was actually Momoko in disguise) about how terrible she feels for losing the pendant since it was made from Sachiko's grandmother's precious ring. Momoko whispers to Beth to go look for it, prompting Beth to do so which buys Momoko time to also look for it without revealing her presence to Beth.
Beth walks by Sachiko's house later and sees Sachiko inside watching her grandmother juggle with footbags.
Momoko and her friends retrieve the pendant and return it to Beth's bedroom unnoticed. Beth then finds the pendant that evening and feels relief, as she goes to the Christmas party with Sachiko wearing matching pendants.
Ay, ¿así que estabas aquí? Llevo el colgante que me dio mi abuela, ¿ves? Te lo pondrás en la fiesta de Navidad, ¿verdad? Se va a ver fantástico que vayamos con los mismos colgantes. ¡Claro! Me dejas probar el de mi abuela.
