From the final season of Phineas & Ferb:
It's all about bees. In the opener, "Bee Day", Isabella and her friends are part of a group loosely based on the Campfire Girls more than the Girl Scouts, and have a learning experience about bees. The second half of the show reveals that one of the girls has a dog, Pinky, who is, like Phineas' pet platypus, Perry, a secret agent. In "Bee Story", Phineas turns the girls into bees, even shrinking them down to insect size, when their bee hive is stolen by an adult obsessed with the royal jelly of bees.
Didn't see "Bee Day". "Bee Story" gets an A.
