Episode Summary

It's a windy day on Sesame Street and Elmo and Telly's basketball is missing! It's a mystery and they need to investigate to solve the problem. Telly writes down what they already know, then forms a hypothesis that Abby must have made the basketball disappear because she's able to do magic. But Abby says it wasn't her. And now Telly's notebook and crayon have vanished…more mystery!

The friends keep hearing a whoosh sound. What can be all around that you can hear and feel, but can't see? Wind! Elmo and Telly test out their new hypothesis and see if the wind made their things disappear. They follow a leaf flying in the wind and find all their missing things. Mystery solved!
