Moose Boy is a tiny drawing hidden on a chip inside certain Nokia 5190 phones. It shows a kid with moose antlers holding a sign that says "IM MOOSE BOY." A Motorola chip engineer snuck it in during production in the late 1990s. You can't see it without a microscope.

Where exactly is Moose Boy hidden?

It's not on the main circuit board — that's what threw people off for so long. It's on a chip inside the crystal oscillator, which is a small metal component on the PCB. You have to desolder the oscillator, crack open the metal casing, then look at the chip inside under 100-200x magnification.

Does every Nokia 5190 have Moose Boy?

Nope. Only some production batches have it. Look for crystal oscillators marked "1284A", "13.0C", and date codes from 1998 (like "9823"). Earlier production runs seem to have the best odds. There's no guarantee even if you find the right markings.

What is silicon graffiti?

It's basically chip engineers hiding tiny drawings on semiconductors. They use the same photolithography process that makes the functional circuits to sneak artwork into empty space on the chip. Engineers have been doing it for decades — you can find everything from cartoon characters to inside jokes. It's gotten rarer because modern chips don't have spare room and companies got strict about it.

What tools do I need to find Moose Boy?

A Nokia 5190, a phone repair kit, precision tweezers, a soldering iron with a desoldering pump, a razor blade, and most importantly a USB microscope that can do at least 100-200x magnification. You're going to fully disassemble the phone and crack open a tiny metal component, so steady hands help too.

Who created Moose Boy?

Nobody knows for sure. It was a Motorola chip engineer who never came forward publicly. The theory is that "Moose" was a nickname for a friend or coworker, and the art style is clearly inspired by the Big Boy restaurant mascot. Just with antlers.

When was Moose Boy discovered?

People had talked about it in chip art circles for years, but the real community hunt started in 2022. The big breakthrough was figuring out that it wasn't on the main PCB at all — it was one layer deeper, inside the crystal oscillator. That's why nobody could find it before.

What We Collect

We run a lightweight analytics script that tracks basic stuff — which pages get visited, how far people scroll, and what links get clicked. That's it. No names, no emails, no IP addresses, no personally identifiable information.

We don't use Google Analytics or any third-party analytics service. The data stays on our own server and helps us figure out which content people actually care about.

Affiliate Links & the eBay Partner Network

This site contains affiliate links to eBay. If you click on affiliate links on this website and make a purchase, we may earn a commission at no additional cost to you. The price you pay is exactly the same whether you use our link or find the listing yourself.

Our eBay links include tracking parameters that tell eBay the click came from us. That's how they know to credit us if you buy something.

Cookies

This site doesn't set cookies on your browser. But when you click an affiliate link and land on eBay, they may set a tracking cookie so they can attribute the sale back to us.

Here's how eBay's attribution window works:

Buy It Now purchases: 24 hours from click
Auction bids: 10 days from click

Those cookies are set by eBay on eBay's domain — we can't see them and we can't control them. Our site is hosted on Cloudflare Pages, which may set its own functional cookies for security stuff like bot detection. Those aren't used for advertising.

Opting Out

You can block or clear cookies in your browser settings any time. Every major browser lets you do this — usually under Settings > Privacy or Security.

Blocking cookies won't break anything on this site. You just won't be tracked for affiliate attribution, which doesn't affect you either way. Same products, same prices.

Third-Party Sites

When you click a link that takes you off immooseboy.com — mostly to eBay — you're on their turf. Their privacy policy applies, not ours. We don't have any control over what they collect.

Changes

If we update this policy, the new version goes up here with a fresh date. We won't quietly make it worse.
