A four-year-old girl has slipped out of her house at 3am and hopped on a bus in the US in a quest to find a snack.

Bus driver Harlan Jenifer said the girl, wearing her purple raincoat, swung her legs in a seat as she chanted: "All I want is a slushie."

Authorities in Philadelphia said the girl's family did not know she had awoken and unlocked the back door to start her trek during a downpour.

They have found nothing amiss at the house and have no plans to file charges.

The bus driver stopped and called police, who took the girl to hospital where she was reunited with her mother.

The father-of-three said he was worried about the girl but found her adventure funny. He said he knew she was in good hands.
