The constant congestion and snoring of Isaak Lasson, 6, baffled his parents and doctors, until an ear, nose and throat specialist snaked a camera up the Salt Lake City, Utah, boy's nose.
"There it was, a ball of fungus," said Isaak's dad, Craig Lasson.
Inside the ball was a dime-sized wheel of soft rubber, a piece of a toy.
Isaak admitted putting "some spaghetti in there that hadn't come out," his father told ABC News, but "We have no idea what it is or where it came from."
The wheel is now treated like a trophy, sitting in a container atop the family refrigerator, and "Isaak thinks it's great. He wants to show it to all his friends," his father said, noting his son has more energy and a better appetite, since he can now smell his mother's cooking.
