As mentioned above, IT feeds off the fear of its victims, which is why it takes the shape of their biggest fears (and as clowns are a common fear among children and adults, Pennywise is its go-to shape), and it also took pleasure in haunting and tormenting its victims precisely because of the fear it provoked in them.
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.
The spider-clown shrinks as the Losers hurl taunts at It, until it's tiny and weak enough that they pluck out its heart and squash it into nothingness. In the end, they defeat Pennywise by, uh, making him feel really bad about himself.
In each adaptation, Pennywise attacks his victims by manifesting the thing they fear the most. For the boys in the Losers Club, that fear includes werewolves, mummies, lepers, evil paintings, and even giant birds.
Stephen King's IT featured an evil entity that can take any shape and feeds off fear, but even this creature has fears, and it's scared of The Turtle.
It's weaknesses are courage and heart. For the sake of spoilers, I won't go too much into the Ritual of Chüd, but suffice it to say that if you want to defeat It, you've got to have the two traits listed above.
Young kids fear "pretend" things.
They fear what might be under their bed or in the closet. Many are afraid of the dark and at bedtime. Some are afraid of scary dreams. Young kids may also be afraid of loud noises, like thunder or fireworks.
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.
Finally, Pennywise is beaten into submission. He scurries away, utters the word "fear," and partially disintegrates before falling into the void. It's a powerful defeat of a powerful monster, and it's satisfaction enough were IT to remain a single film.
The cinematic adaptation of Stephen King's IT Chapter Two depicted the satisfying death of Pennywise while subtly hearkening back to Pennywise's first 1988 victim, Bill's brother Georgie.
According to It, when humans got scared, "all the chemicals of fear flooded the body and salted the meat". This is why he prefers to feast on children -- their fears are simple, pure, and powerful compared to the complex, pathological fears of adults.
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.
This is explained in the Book, it's because once “It” was “killed” there was no longer a subconscious bond between them in which they reunited back together to kill the beast.
The only other being in that empty, dead space is Maturin: a giant, benevolent turtle that ends up helping the losers' club in their fight against It.
Pennywise's Kills Add Up Over Time
The number is then multiplied by the number of times Pennywise has awakened -- once every 27 years throughout the 270-year history of Derry, equaling ten times -- to come up with a final tally of between 12,000 and 18,000 dead.
Pictures] In King's book, Georgie Denbrough apparently dies from complications due to having his arm ripped off by a reptile-toothed clown. As he reaches into the sewer to retrieve his boat, Pennywise grabs Georgie's arm and the boy starts flopping around and screaming.
In some versions, Georgie bleeds to death by the sewer. But in the 2017 iteration, Georgie attempts to crawl away, but is dragged into the sewer by Pennywise, never to be seen again. But because his body isn't found, it prompts big brother Bill to go looking for him. Warner Bros.
In It, the symbol of the red balloon is turned on its head. What symbolizes a child's sense of imagination is manipulated to lure children to the clown, Pennywise (Bill Skarsgård).
Red balloons are Pennywise's calling cards, and he often uses them as bait to kidnap children.
In the novel, it's explained that Richie got a vasectomy so he could have unprotected sex without worrying about kids, but the vasectomy “failed and the tubes regrew”, and he was actually fertile, yet he didn't get any of his partners pregnant.

Once there, IT adopted its usual pattern of hibernation that lasted between 27 and 30 years, awakening to kill and eat and then going back to sleep.
The Losers Club is a group of seven eleven-year-old misfit children who are united by their unhappy lives.
IT, Georgie's fear is IT, an evil creature in his basement that smells of garbage and wants to pull him through the basement stairs and eat him(this creatureis entirelymade up).
The new version is much more gruesome and intense during this particular scene. Also, Pennywise the dancing clown went through a complete transformation in the making of this film. Tim Curry played pennywise in the old movie. This version was scary in its simplicity.
