There’s a new friend on Sesame Street! Karli is living with her foster parents, Mr. Clem and Ms. Dalia, until her mom can take good care of Karli again. Elmo and Abby are drawing pictures of their families and invite Karli to draw too. Karli says her drawing will help her remember her mom. This gives her an idea! She asks Mr. Clem and Chris for a box to put all the things that remind her of her mom in one place. Elmo and Abby think having a box is a great idea. All three go off to collect things that remind them of their families and place everything in their very own special treasure boxes.
