The mystery of why Pennywise the Dancing Clown preys on children instead of adults has haunted IT fans for years. Now, with IT: Welcome to Derry expanding the lore, director Andy Muschietti has finally offered a clear explanation — and it fits perfectly within Stephen King’s terrifying universe.
Fear Is Strongest Where Belief Is Purest

According to Andy Muschietti, Pennywise survives on fear, and children are uniquely vulnerable to it. Kids naturally believe in things adults dismiss — monsters, shadows, and unseen dangers. This openness makes their fear more intense, richer, and easier for Pennywise to manipulate. In the world of IT, fear isn’t just an emotion; it’s fuel, and children provide the most potent source.
Welcome to Derry Shows a More Brutal Pennywise
HBO Max’s IT: Welcome to Derry dives deeper into Pennywise’s 1962 cycle, portraying a far more aggressive and sadistic version of the creature. The prequel series doesn’t waste time showing how quickly Pennywise targets children, using elaborate psychological tricks and shapeshifting horrors. Unlike adults, the young victims often face these terrors alone, making them easier to isolate and consume.

Why Adults Rarely See the Truth
One of the most disturbing themes in IT is adult denial. Grown-ups in Derry frequently ignore or rationalize the strange events around them. Muschietti explains that adults struggle to accept supernatural fear, which makes them harder for Pennywise to fully control. Children, on the other hand, don’t question what they see — they feel it, believe it, and suffer from it deeply.
Pennywise’s Biggest Mistake: Underestimating Kids

Ironically, Pennywise’s obsession with children becomes its greatest weakness. As seen in IT: Chapter One and Chapter Two, the Losers’ Club learns to turn belief into power. By confronting their fear together, they strip Pennywise of control. The creature that thrived on terror ultimately fails because it never expected children to fight back.
In the end, Pennywise targets kids not because they are weak — but because their belief makes fear real. And when that belief shifts, even an ancient evil can fall.
