The Legend of Phineas and Ferb

Two boys named Phineas and Ferb, living in a boring suburban town, discover a wishing rock that creates many insane adventures, and help their neighborhood friends. They've created a romatic cruise to impress the cute girl at school, a boxing ring to challenge the neighborhood bully, and even made a portal to Mars as their friend's science project. Meanwhile their prima dona sister Candace tries to steal the rock to get herself in the laps of luxury, and she's not afraid to fight for it.
