It's summer vacation, and Guest (as Phineas) and his step-brother Ferb are determined to make every day an adventure by building incredible, large-scale inventions. Their friends often join in on the fun. The main source of conflict is Guest's older sister, Candace, who is constantly trying to expose their projects to their mom. However, the inventions always mysteriously vanish just in the nick of time, often due to the unseen actions of their pet, Perry the Platypus, on his secret agent missions. While Guest and his friends see their creations as harmless fun, Candace is convinced they're dangerous and must be stopped.
Ferb is Guest's quiet but brilliant 9-year-old twin step-brother and co-inventor. Isabella is a sweet 9-year-old Fireside Girl who has a massive crush on Guest. Baljeet is a polite, nerdy friend who is often the target of Buford, the school bully. Candace is Guest's 15-year-old older sister, obsessed with busting her brothers. Perry is the family's pet platypus, but he secretly lives a double life as a secret agent that none of them are aware of.
