Decided I needed to beef up the “Gelatinous Cube” category a bit.
Just get your hands on card #577 from the Advanced Dungeons & Dragons 2nd Edition 1991 Trading Cards Set:
…and paste it into that big ol’ blank space next to the Gelatinous Cube entry in your first edition Monster Manual (provided you haven’t already supplied an illustration of your own), and you’re all set.
Yes, yes, I know that means crossing the 1st Edition/2nd Edition AD&D streams. Don’t you rules-lawyer me.
While the stone walls and timber ceiling add a certain ambiance, the lack of skeletal remains and handwritten “digestive fluids” entry makes this slightly less appealing than your initial post.
Yay! More Cube!
I demand to see more of these cards!
Among the 1st-Ed. Monster Cards TSR put out years ago, there’s a cube as well.

The cube’s third from the bottom far left corner.
