Press kit description
“In When You Wish Upon a Pickle, a mysterious wish machine appears on Sesame Street and the magical pickle inside starts granting wishes. Before long, the gang learns they need to be careful what they wish for – especially when they find out he’ll only grant one wish per customer! 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. Cookie Monster’s wish for more cookies results in more Cookie…Monsters! 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!”
