When Elmo wishes to be a grown-up and run Hooper's Store, he switches bodies with Chris. When Ernie tries to help his friend achieve his dream of becoming a TV meteorologist, Bert ends up trapped in the television, dashing from show to show.

Abby Cadabby teams up with her favorite storybook detective – brought to life by a wish, of course – to try and solve the mystery of what’s going on in the neighborhood. The adventure continues until an unlikely (and grouchy) hero intervenes!
