On Bee Day, Phineas and Ferb create an inflatable pool for their mother while Perry the Platypus tries to stop Dr. Doofenshmirtz from acting like a queen bee. Meanwhile, Isabella and her fellow scouts seek Phineas and Ferb's help to earn their beekeeping badge.

Phineas and Ferb, stepbrothers eager to make the most of their summer vacation, constantly engage in mischief and invent bizarre gadgets, like a giant skateboard, much to the annoyance of their older sister, Candace. She attempts to expose their antics to their mother, but Phineas and Ferb always manage to cover their tracks. Their adventures are shared with Perry, a platypus who leads a double life as both a pet and a secret agent.
