Phineas and Ferb Hawaiian Vacation

During a Hawaiian family vacation, Candace finds a cool lava rock necklace and is plagued with bad luck, so a native tells her she must take it to the top of a volcano, which spoils the cool, calm vibe she learned from a Hawaiian yoga instructor. Phineas and Ferb go with Candace and along the way, they ride a few waves with pro surfer Laird Hamilton. Meanwhile, Dr. Doofenshmirtz is also at the same volcano, trying to make the population less intelligent with his "De-Evolution-Inator."
