Ladies and gentlemen, boys and girls of some ages. It’s me, your favorite Zebra, Larry Larkmo The PranKing Zebra. I have a great new gag item that is sure to make humans go crazy! Imagine if you will, something so stupendous, amazing and outright mean! No I’m not talking about my ex-girlfriend, I'm talking about the Larkmo Annoying Sound Device. Made from space age polymer plastics, moon rock dust and leftovers…ok it's not really made of that, but it is made of quality components built to last.


What exactly does it do? Glad you asked. It's a very small random noise maker. Just turn it on, pick one of the available noise options and hide it. It can be a room, office or any other space you know someone will be in for an extended period of time. The device will sound off automatically driving your victim mad. Best part is it will continue to sound off for what seems like forever. Makes a great office prank. Use two of them in tandem to make it even harder to locate where the noise is coming from.

  • SO SMALL YET SO SINISTER. How can one small noise device create such havoc. This annoying beep prank will become your favorite of all pranks and practical jokes. Super easy to use. Simply turn it on, pick a sound and hide it. All that's left to do is watch and hear your victims lose their mind.
  • WHY OURS? Most other annoying beep prank noise makers just don't last as long as ours. They use a battery that lasts a few days, we use a battery that lasts months and even years. Keep the beeping laughs going. Makes a great revenge prank, joke or gag.
  • MULTIPLE SOUNDS. Why Limit yourself to a sound machine noise device with only one sound? Ours has multiple different noise options. Two different annoying cricket sounds, a beep noise, and  lastly a computer tech sounding something or other thing-a-ma-bob that is so annoying, it will have people running for their sanity.
  • PERFECTLY TIMED INTERVALS. Lets face it, this might be the number one complaint form all others. Some go off way too often, while others don't go off enough. If it goes off too often it will be easily found, if it doesn't go off enough it won't be annoying enough. We’ve timed ours perfectly, at least we think so. See interval chart in the pictures for info on how often it sounds off.
  • HOW TO USE. Turn it on, pick a sound and hide it. So easy you might want to buy two. Hide them at a distance from each other for double the laughs. Once they think they have located the sound, the other one goes off and throws them off. Makes a great office gag or any other work place location.
