Out to Launch (Phineas and Ferb)

Lawrence is preoccupied with buying and naming stars online. He buys one for Phineas and Ferb, and also one for Candace. Candace and Isabella are preoccupied with a turn-around dance where the girls ask the boys out. Candace thinks Jeremy will refuse; and Isabella keeps getting interrupted when she asks. Phineas and Ferb build a rocket to visit their star. Heinz Doofenshmirtz is also in space, seeking revenge on an adolescent nemesis.
