Slimey and four other worms get into a spaceship headed for the moon.

Big Bird hears some wonderful music coming from Celina's dance studio. It makes him want to dance, so he does as he makes his way upstairs.

At the park, Big Bird welcomes the viewer to Sesame Street, and encounters a sad Snuffy. Snuffy explains that he's sad because of ... tap dancing.

Gabi makes her way over to Oscar's trash can from the yard to see what Oscar is doing. In preparation of Slimey's return from the moon, he's getting Slimey's bed ready. Gabi bets that he's excited, but Oscar counters that it's just Slimey: his "little mud button," his "little space hero back from the universe at last." Oscar's spent a lot of time planning his return with a mint laid out on the bed, and a fresh apple to eat. Gabi gets that he's secretly happy to have Slimey coming home today, but reminds Oscar that he still has to get from space back to the Earth.
