Phineas: "What do you think the scariest thing was, Ferb?"

Phineas: "Yeah.....yeah, where did that come from?"
-Phineas and Ferb on the baby head.[source]
The inexplicable Giant Floating Baby Head is a mysterious being that appears very randomly. While they tend to appear in some of Phineas and Ferb's or Dr. Doofenshmirtz's Big Ideas, they are clueless as to where they comes from.
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").
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. They were 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").
They were 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").
They were 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").
Numerous giant floating baby heads of various sizes appeared in the 4th Dimension during "Brand New Reality". (Phineas and Ferb the Movie: Across the 2nd Dimension)
Then, the baby head, appeared as an implement for constructing the tower. ("Escape from Phineas Tower")
- The giant baby head came, according to Dan Povenmire, "one board panel drawn by Mike Diederich and one of our directors, Rob Hughes thought it was hilarious and made a whole bit about it. Now it shows up all the time."
- A mechanical giant baby head appeared in "Put That Putter Away".
- The baby head is seen in the Phineas and Ferb video game.
- In the song "Technology vs. Nature" during the line "when a child cries out in the night, it's rarely for the washing machine" an identical baby with a different hair color is shown.
- As of "Misperceived Monotreme" and all its subsequent appearances, the baby head's eyes are more oval shaped rather than the circle shaped eyes seen in previous appearances.
- The Giant Floating Baby head appears in the Camp version of the online game Summerizer, behind the mountains when you combine Perry and Agent E.
- Someone had a baby head costume for Halloween in "That's the Spirit".
- In "Monster from the Id",they appeared in the song "Deep Into Your Mind", as the fact, that Candace is afraid of the baby.
- In "Fly On the Wall", Candace was briefly transformed into the Giant Floating Baby Head after she was accidentally transformed into a fly.
