[TOMT][PC Game][2000's] The RECTANGULAR DISC for the SpongeBob Movie Game Demo

Back when I was a kid we got some cereal with a promo item in it - It was a rectangular CD for the Spongebob The Movie Game (I'm pretty sure). The disc itself was approximately the size and shape of a business card.

Yes, the disc was squared off on the edges. A rectangle, not a circle. This isn't a joke.

The infuriating thing is that there are absolutely NO images of this online at all. If you try searching for Spongebob Square/Rectangle demo disc/k you don't get any results for it. There's nothing on Ebay (globally), there's nothing on FB marketplace that I can find, I can't find it amongst retro game collections. It almost feels like this thing never existed... But it did. I used to own it.

So does anyone have any pictures of this disc? I'm not even looking for the disc itself to collect or anything, I just want to see images of it. I want to know that someone somewhere out there still has it.

Maybe I would buy it from someone. At this point it's burned into my memory so utterly completely that it's almost maddening.
