Cry havoc!

Let loose the pranks of war in your workplace, dorm, or wherever with our Annoy-a-tron Prankster Pack. There's someone you'd like to torture in your office: maybe it's that guy who is always creating emergencies for you because he doesn't plan ahead, or that lady who is trying to throw you under the bus for something that was her fault... or maybe it's your work spouse, because they are just so much fun to prank. Or does your best friend maybe need a cricket trapped in a cinderblock during finals? Let us help you in your mischief making!

The Annoy-a-tron Prankster Pack contains:
  • Annoy-a-tron: Periodic beeps and sounds make your friends crazy hunting for that ANNOYING NOISE.
  • Ringtone Annoy-a-tron: RINGING AND BUZZING will drive friends bonkers looking for the missing phone!
  • Eviltron: Unsettling spooky sound effects SCARE THE CRAP out of your friends.
Let us know about your pranking adventures! We love to hear your stories of mayhem.

Update: 8/2/17: Turns out when we revamped these in 2015, we made it so they annoyed our fans instead of the intended targets. That definitely wasn't our intent, and you let us know. We told our warehouse to box up all the ones they had left and deliver them to a New Mexico landfill and never speak of them again, while we set out to recreate the original magic. We think we've done it. This batch is louder. The batteries (now replaceable) don't drain as quickly. And we performed hands-on product testing here in the office. We can confirm they are highly annoying. We hope y'all will give us another chance....
