Phineas and Ferb create an orb that allows them to pass through solid objects and to ultimately, help them retrieve Mom's favorite guitar pick for her gig at the Mayor's Day Festival. Candace sees their orb as the perfect way to bust them and brings it to Mom, but en route to the festival, the troublesome Wilkins Brothers put a kink in her plans. Meanwhile, Dr. Doofenshmirtz attempts to destroy a statue erected in his brother Roger's honor.
