Not kool.

Suffolk police are seeking “multiple” suspects who were caught on surveillance footage busting down a fence in East Northport last month as part of “The Kool-Aid Man challenge” that’s spread across social media in recent months.

Footage released by authorities Monday shows four people throw themselves into – and knock over — different sections of a Long Island homeowner’s fence. The four are then seen quickly fleeing the scene of the March 18 incident as a fifth person joins them in running away, according to the footage.

Suffolk County Crime Stoppers is offering a cash reward for any information that leads to an arrest. Tipsters can remain anonymous, police said.

This isn’t the first time a Long Island home has been targeted due to the “Kool-Aid Man challenge” that mimics past commercials of the iconic brand’s bright red mascot breaking down walls, shouting “oh yeah” and delivering the kids’ drink.

Six teens, ages 12-18, were arrested in February after they took video of themselves bursting through fences in Suffolk.

The unruly teens appeared to target four homes that night, cops said.

The five juveniles and one 18-year-old were charged with several counts of third-degree criminal mischief and fourth-degree criminal mischief.
