Wearing their khaki adventurers’ vests and light-up bracelets, a dozen kids raise their little fists in defiance.

“You’re horrible,” one of the braver ones shouts at the bad guy known as Joules Volter. “Thanks, Captain Obvious!” the bald, evil mastermind hisses back.

This melodramatic scene played out near the end of “Pip’s Island,” a hands-on experience aimed at 4- to 10-year-olds. The 15,000-square-foot installation in Times Square is like a “Sleep No More” for small ones. There’s no formal seating. You and the kids walk from room to fantastical room during the hour-long, interactive show.

The production is mostly live-action, but there’s also animation, eye-popping visual effects and puppeteers. (Volter is one of the live ones.)

My 8-year-old son, Bobby, fully embraced his role as part of the expedition to the titular mythical isle. The mission? Ridding the place of Volter and his crafty (puppet) mole spies by solving a series of problems, including riddles and letter games. Right answers earned the players “sparks” in the form of digital badges, while actors playing the trusty hero, Pip, and his sidekicks, Pebble and Finn, were there to help out.

Along the way, kids operate a flying “steam ship” by wrangling handles and levers, and decorate fake cakes with magnetic frosting in a bakery.

Bobby’s favorite stop was in a bubble-filled chamber that makes you feel as if you’re underwater. Here, a fairy-type character called Shelly breaks into song and leads a conga line around the room.

Adults trail the kids through the different rooms, so they’re never alone.

Cameras aren’t allowed in the attraction itself, but at the exit, grown-ups can snap a picture of the whole team of adventurers — which, since “Pip’s Island” opened, has included the offspring of Sienna Miller, Neil Patrick Harris and Jane Krakowski.

Bobby and I may not be on the A-list, but as we strolled back to the subway, he pronounced his visit “Amazing!”

“Pip’s Island” runs Wednesday through Sunday at 400 W. 42nd St. Tickets start at $39.
