It is implied in Phineas and Ferb: The Movie Game: The Dimension of Doooom! that she has feelings for Ferb, although this is never verified in the film. Because the game does not follow the events of the film, this attachment may be non-canon. In the episode's sequel, no such relationship was addressed. However, in the short film Disney's Hollywood Studios Before Sunset, it is revealed that Isabella likes Ferb after he saved her from being hit by a car. In the comics, they have a similar relationship. After Ferb is turned into a doll, he is given life by the magic within Isabella who also gives him a new body. This new body is designed specifically for her and resembles Ferb except with black hair instead of red. She also creates clothes for him to wear. Together, they go on adventures in Ferb's world while trying to find a way to return him to human form. Isabella first appears in the comic book series titled "Phineas and Ferb: Mission Marvel". She and Ferb are working together to save everyone else from Dr. Heinz Kabongo who is planning to use his robot army to take over the world. They agree to work together because they need all the help they can get. During the mission, it is discovered that Dr. Kabongo is actually Dr. Heinz' twin brother Vincent who went crazy when he found out his brother was going to kill them.
