Pennywise, also known as It with a capital I, is some messed up thing that kills everybody. It can shapeshift into anything, and It's general form is a clown, but It will disguise Itself into the worst nightmare of the person it is tormenting (such as Mike Hanlon's bird.) It also sabotaged many plans that would have put the world at peace. It chooses who sees It, and It can kill anyone It wants to. If you see a suspicious clown with orange pom-poms that looks like the one at the right, don't even bother running, because you should know already that you are screwed.
It is believed Pennywise has been created by the master of horror, Stephen King, representing harmony and love between all people, especially when he was on his way to clown, which amused the children and people around them. Created about 80 BC to the first novel "IT", but the reality is that it was the monster who created the writer, it would not be anything but a doll through which exploits the fears around the world, transforming it into Best Sellers, sucking it like Dan Brown.
Originally from a place called the Macroverse, Pennywise is an alien being that arrived from space in a asteroid. To survive devours children, every 27 years or so (which is what does your digestion), and to draw them into his mouth used and what scares the kids happy: It disguises condom with toupee.
It is suspected that lives in a gravity chamber or stolen from the Russians during the Cold War and / or drugged lives, because it keeps saying instead "Theeeeeey aaaaaalll floooooooat". It is giving away balloons (anti-gravity condoms that make you cross-eyed to the laws of physics) that explode, God knows why, you stain of blood. It has been speculated that the blood would clown, that living in the sewers has a multitude of diseases of all kinds, which explains the mysterious deaths in Derry.
