Phineas and Ferb: Last Day of Summer (2015)

Synopsis

On the inevitable 104th day of summer vacation, the season — and the series — is quickly coming to an end, and it’s Candace’s last chance to bust her brothers; who build huge playground equipment for the finale of summer. She is quickly foiled, but when she goes to return a DVD to Vanessa and finds Dr. Doofenshmirtz’s Do-Over-Inator, she finds an opportunity to redo the day, which results in other consequences like rips in the space-time continuum, the shortening of days and the disappearance of her brothers.
