You'll float too”. Although the phrase is represented differently in the book and the movies, it has the same meaning in both, as it's Pennywise's way of subtly telling its victims (mostly young children) that they will die.
The simplest and most obvious interpretation is that all the talk of floating is a reference to the fact that Pennywise (aka the titular "It") murders his victims and drags them down to the town's sewer system where he dwells, which is full of water. And what do dead bodies do in water? That's right — they float.
By taking the shape of the children's deepest fears and thus scaring them, IT has a great amount of power over them, and fear makes it difficult for a child to fight back.
Pennywise always lets the children know that they'll float, float just like his helium balloons.
Stephen King's 'IT' introduced readers to a one-of-a-kind creature that can take any form, the most common one being Pennywise the Dancing Clown, and as menacing as it is, this creature has one big enemy it's truly scared of: Maturin, the turtle.
It taught me a whole lot of important life lessons as a child, but the chief among them—the most important of all and the one I have never, ever forgotten—is this: If Pennywise takes the form of whatever it is you fear the most, then there's nothing to fear but fear itself. Fear is the only real enemy.
They reach the conclusion that Pennywise has all of the adults under some sort of spell that prohibits them from seeing him. The adults of Derry are shown to be villainous in their own right as well. The adults of Derry are shown to be true villains of the story in the same way as Pennywise.
The story follows the experiences of seven children as they are terrorized by an evil entity that exploits the fears of its victims to disguise itself while hunting its prey. "It" primarily appears in the form of Pennywise the Dancing Clown to attract its preferred prey of young children.
It : I'm every nightmare you've ever had. I'm your worst dream come true. I'm everything you ever were afraid of. Pennywise : Kiss me, fat boy!
The new It, with Bill Skarsgård portraying Pennywise the clown, looks absolutely terrifying, and that was especially true for the child extras who worked on the film. Apparently, Skarsgård was so scary in the role of the sadistic clown that he actually made kids cry on set.
Pennywise offers Georgie his boat back, but when Georgie attempts to reach out to it, Pennywise grabs Georgie's arm and bites it off, leaving Georgie to bleed to death in the rain.
That hunger for tasty, tasty, beautiful fear is pretty much the sole reason It returns to Derry, Maine every 27 years to torment and feed on the townsfolk before retreating into a new cycle of slumber.
Pennywise feeds on fear, mainly childrens fear. In the 2017 film pennywise is seen retreating from the kids when they conquer their fear of him and start to fight back.
IT thrives on chaos; an exact 27-year pattern is way too predictable for a being of pure evil. Rather, IT wakes up roughly every three decades, and stays away for a different period of time.
Down in the sewers, during their final encounter, it's much of the same. Mike brings the gun he uses to kill livestock, and the rest of the Losers come prepared with more rods. Beverly deals the final blow by putting one straight down It's throat.
Stanley's Head
After Stanley's untimely death in Chapter Two, Pennywise uses a vision of child Stanley's severed head that has been transformed into a grotesque spider-monster to terrorize the remaining members of the Losers Club.
It disguises itself as many frightening things in the movie. Pennywise can morph his mouth into a giant gaping mouth with layers of sharp teeth which he uses it mangle and eat his victims. This is all done with CGI. Two children are killed by Pennywise on screen.
In the novel, It's origins are nebulous. He took the form of a clown most frequently, Mr. Bob Gray or Pennywise, but his true form is an ancient eldritch entity from another universe who landed in the town that would become Derry by way of an asteroid and first awoke in 1715.
The Spider, the true form of IT in the physical plain of existence. Throughout the novel, It is generally referred to as male. However, late in the novel, the characters come to realize that It is most likely female, due to its true form in the physical realm being that of a giant pregnant female spider.
One of the biggest shocks was Pennywise the Clown eating a child's hand, which did in fact make its way into the movie. But it was an even more disturbing scene that had to be cut in the end, one that saw Pennywise eating a baby.
Kersh is Pennywise's daughter.
Appearing like a comet or asteroid, It landed on Earth at what is initially a nondescript time long ago. Later on in the film, when the Losers enter It's Lair, they realize they're standing in the ground zero crater of an asteroid right beneath Derry.
What symbolizes a child's sense of imagination is manipulated to lure children to the clown, Pennywise (Bill Skarsgård). Pennywise's most notable ability is to manifest as each of the children's fears. Whenever the red balloon appears, it signals that Pennywise is close, if not already present.
