His teachers even complained that the 7-year-old was disrupting class with his whistling.
It wasn't until doctors put a camera down his throat and found this was no laughing matter.
It wasn't a sound effect, it was actually a whistle stuck inside Hector Flores, Jr.'s lungs.
Nearly a month ago, the boy was playing in a pool when he swallowed a part from inside a plastic toy duck that makes that whistling noise.
Two weeks later, his mother noticed the strange sound when the Bronx boy had a laughing spell during a shopping trip.
"I said, 'Did you whistle?' 'Yes mommy I whistled.' A man at the bodega said the boy whistled," his mother said.
So, his parents took hector to the emergency room at /*Bronx Lebanon Hospital*/.
"They said he didn't have anything. That it was probably a psychological issue with the child. They concluded the child had a lot of fecal matter," his father said.
They were given pills for a digestive problem.
Still worried, his father recorded the whistling and showed the video to doctors at /*Montefiore Hospital*/ who the used a camera to find the whistle in his respiratory system.
Doctors performed a simple 45 minute surgery with an endoscopy.
The whistle was in one of the arties near his lungs.
Hector's parents say this is proof to always follow your parental instincts.
A Montefiore spokesperson confirms the boy was a patient but couldn't go into specifics.
A Bronx Lebanon spokesperson says the hospital is also aware of the patient and that it gets upwards of 130,000 visits a year and takes pride in its services any concerns will be fully investigated and address.
