Everyone's favorite furry red monster is back with a brand-new special to teach us the importance of standing up and speaking out when people are treated unfairly.

Silliness and surprise twists abound in the half-hour special, in which Elmo teams up with Abby Cadabby via video chat for a virtual scavenger hunt. Aided by Sesame Street friends Big Bird, Grover, Rosita, Oscar the Grouch, Bert and Ernie, Elmo's dad Louie, and tiger Mr. Stripey, the duo invites children to join in the search for all seven items on their list...along the way, "Monster Foodies" Cookie Monster and Gonger whip up a tasty summer dessert, Amy Sedaris shares an easy craft the whole family can make, and Gabrielle Union leads Elmo and Abby in a sweet sing-along.

In the tradition of the Dickens holiday classic, Nature Cat is bursting with what he thinks is “Christmas spirit,” and wants to celebrate with lots of presents for himself, and by decorating the woods with bright lights and loud festive music for everyone. Fa-la-la, that doesn’t sound like Nature Cat? Daisy, Hal and Squeeks are upset because Nature Cat’s desire to celebrate Christmas in a great -big -way is causing problems with their friendship, as well as bothering all of the animals in the woods. It’s not until Nature Cat is visited by the spirits of Nature Past (Daisy), Present (Squeeks) and Future (Hal) on Christmas Eve. But can he finally change and learn the true meaning of Christmas in time for the holidays?

C is for Celebrate! Join host Joseph Gordon-Levitt and the residents of Sesame Street - human and monsters alike - to celebrate 50 years of learning, laughter, and love. Familiar felt faces like Roosevelt Franklin, Don Music, Sherlock Hemlock, and the Amazing Mumford join celebrity guests Norah Jones, Nile Rodgers, Sterling K. Brown, Meghan Trainor, Patti LaBelle, and Elvis Costello in this heartwarming special.

While playing Hal's Hole Hootenanny, Hal accidently digs up Bad Dog Bart's second buried treasure map. The map leads to Bad Dog Bart's stolen loot of cat toys, which brings back emotional memories for Nature Cat of a stolen family cat toy!

Nature Cat can’t wait to get outside for a day of backyard nature excursions and bravery! But there’s one problem; he’s still a house cat with no real instincts for nature. That doesn’t stop this passionate and curious feline, who loves learning and experiencing all he can about nature.
