How did Percy Jackson ruin a perfect bus in The Lightning Thief?

Percy Jackson didn't exactly *ruin* the bus in *The Lightning Thief*. He actually saved it from a monstrous attack.

Here's what happened:

* The bus Percy and his friends were on was attacked by Furies, mythological creatures sent to capture Percy.

* The Furies caused chaos, throwing the bus around and making it spin wildly.

* Percy, using his demigod powers, fought off the Furies and managed to stop the bus from crashing.

While the bus might have been slightly damaged in the fight, it was ultimately saved from total destruction thanks to Percy's heroic actions.
