Police and paramedics rushed to Crocheron Park in the Bayside neighborhood of Queens at around 7:40 a.m. after a woman out for a morning jog found the "baby" lying face-down in the grass.
Detectives descended on the park in droves to look for evidence. A crime scene tent was set up. Yellow tape blocked off the area where the discovery was made.
Police initially reported the child was three months old and had been pronounced dead at the scene of an undetermined cause.
At some point, though, a closer inspection showed the object in the grass was a doll or some sort of theatrical prop, with its skin apparently purposely colored to resemble decomposing skin.
One giveaway was the baby's T-shirt, which read, "the crawling dead."
The red lettering wasn't initially visible because the doll was on its stomach.
"It appeared to be a baby with discoloration consistent with signs of prolonged death, but thankfully, it was actually a lifelike prop," Fire Department spokesman Myles Miller said.
The error was discovered when personnel from the city's medical examiner arrived to retrieve the body.
Police said the episode is under investigation. The Fire Department's Emergency Medical Service was also doing a medical review, Miller said.
