This guy’s the Scrooge of Halloween.

A fedora-wearing ghoul was caught on camera smashing holiday pumpkins on a Brooklyn stoop — twice — and vigilante neighbors are teaming up to catch him, according to the victim and police.

“What bothers me is this is an adult,” fumed Herbert Kalloff, 63, who lost two pumpkins to the jerk. “I can’t believe it.”

The out-of-his-gourd vandal first struck at around 2 a.m. on Sept. 29, when he stumbled up to Kalloff’s Bay Ridge porch and slammed a painted pumpkin into his front stairs.

Surveillance footage shows the clumsy criminal trying three times to destroy the decoration — bouncing it unsuccessfully against the sidewalk — before it finally busted open. He then bolted from the home on 81st Street near Third Avenue.

He then returned to the home again Wednesday — this time sporting a leather jacket and fedora — as he went to town on Kalloff’s replacement pumpkin, the footage shows.

But Kalloff refuses to have his Halloween spirit crushed.

He said neighborhood sleuths, some working together through a community Facebook page, sent him “a name and an address” that would help lead him to the jerk.

Although cops are searching for the man, Karloff said he plans to take matters into his own hands.

“I think I’ll be better off handling this guy than [police] would,” he said, without elaborating on what he planned to do. “I don’t really want to bother

them with this little thing.”

Kalloff, who is a retired sanitation worker, added he “knows how to deal with ‘garbage.’” He said he has never met the smashing suspect.

On Friday, police were also on the hunt to catch the man, the NYPD said in a Facebook post

“Does anyone recognize this tough guy pumpkin smasher[?]” the 68th Precinct wrote in the post, which featured screengrabs of the man hurling the pumpkins at the ground.

After the second smashing, Kalloff said a kind neighbor left third pumpkin on his stoop with a note. It read, “Some ppl can be very mean. I just wanted to spread some Bay Ridge love.”

The new pumpkin may come in handy as a booby trap, if the jerk targets him again, Kalloff said.

“I put vaseline all around the new pumpkin — so we’ll see what happens. Maybe he’ll drop it on his head [next] time.”
