Giant Floating Baby Head

The  is a mysterious being that appears very randomly. While he/she tends to appear in some of Phineas and Ferb's Big Ideas, both Phineas and Ferb are clueless as to where he/she comes from.

Victorian times
In Victorian times, an identical baby head entered the Best Monster Contest. It is not known if the baby head has been around for hundreds of years, or that was just a lookalike ("The Monster of Phineas-n-Ferbenstein").

Present life
The giant floating baby head first showed up when Phineas and Ferb tried to help Isabella get rid of her hiccups by building a haunted house in the backyard. After Candace went through the haunted house to find her brothers, she complained about how outrageous the house was and asked why the giant floating baby head was even there. The baby head cried after Candace told him/her to be quiet. He/she was also in the haunted house's elevator when Candace was going to use it and was abruptly told to leave the elevator. At the end of the day, Phineas and Ferb relaxed in the tree and thought about what the scariest thing they did was, and Ferb stated that it was the Giant Floating Baby Head. They both suddenly wonder where it came from anyway ("One Good Scare Ought to Do It!").

The baby head showed up again as one of the supplies being delivered to the Flynn-Fletcher house when Phineas and Ferb build the monster truck arena in their backyard to help Candace learn how to parallel park although it was not in the arena or in/on the monster truck. ("It's a Mud, Mud, Mud, Mud World").

He/she reappeared on a handcart behind the boys and Candace when they built the PF 5000 Animatron. The baby head was shown being lifted upwards ("Out of Toon").

The baby head was also one of Chez Platypus's customers and was allowed by Buford into the restaurant ahead of Candace and Jeremy ("Chez Platypus").

He/she was also behind Candace's window as Candace was talking to Stacy about her text message to Jeremy. The baby was being carried by a lever for unknown purposes ("At the Car Wash").

He/she visited Heinz Doofenshmirtz when his foot was broken, and somehow managed to sign his cast. He/she was accompanied by Dr. Bloodpudding at the time ("The Bully Code").

He/she is briefly seen in Livin' in a Funhouse, in the line "The bathtub is your bed and a floating baby head" ("Misperceived Monotreme").

He/she was among the various people in Phineas and Ferb building. Before the building's completion, Phineas mentioned putting something next to a giant gorilla head, which is most likely a reference to this ("The Doof Side of the Moon").

The baby head was also seen during the song Carpe Diem ("Rollercoaster: The Musical!").

Numerous giant floating baby heads of various sizes appeared in the 4th Dimension during Brand New Reality, maybe that's where they come from ("Phineas and Ferb The Movie: Across the 2nd Dimension").

Months after summer, on Halloween, someone had a baby head costume, he/she was shown a few moments ("That's the Spirit").

Then, the baby head, appeared as an implement for constructing the tower ("Escape from Phineas Tower").

In Candace's mind, he/she appeared in the song Going Deep into Your Mind, as the fact, that Candace is afraid of the baby ("Monster from the Id").
