The Ninja Poop Pen

Kamhi World’s Ninja Poop Pen is a 7.5-inch ballpoint pen shaped like a brown cartoon fighter in a stealth outfit, red headband, and boxing gloves. Two levers control the punching arms independently, while button presses add combat noises and fart sounds. The listing says it writes with real ballpoint ink and arrives with replaceable batteries, so the product combines an actual pen with a small action toy rather than disguising an empty plastic figure as stationery.

It fits a school-age collector, a teenager’s desk, a party-favor bundle, or a family gift exchange where bathroom humor is already welcome. The separate arm controls make it more interactive than a single sound button, and the ninja styling gives the recipient a reason to stage tiny bouts with another fighter from the series. Batteries, moving levers, and sound effects also mean it is not a quiet classroom pen or a toddler object. The useful writing tip may extend its life, but the 7.5-inch body is intentionally conspicuous; this is for someone who wants their pen to interrupt the pencil cup before it ever reaches the page.
