To this day, my favourite NPC in an official #dnd module is Glabbagool, the sentient Gelatinous Cube from Out of the Abyss.

What's yours?

I like how Themberchaud use to be just a throw-away character in Out of the Abyss. But people loved him too much.
I still kinda like Glabbagool, the sentient Gelatinous Cube from that adventure.

Tonight, in D&D:
Oozes defeated, the Orphan-makers, & Glabbagool, escape through a river.
Following a worn path, the city of Blingdenstone!
Glabbagool disappears and guards guide them in.
Gobbo sends a message to his fathers, and a ritual ends their curse.
A meeting with the city's leaders!

Tonight, in D&D:
Trying to reach Bildungstone, an Underdark cave-in!
The only way is through an ancient temple
Strange carvings of tentacled creatures.
Grey oozes fought off.
A strangely talkative ooze named Glabbagool.
Treasure found, more oozes attack!

I wonder how far I can indulge in my Monsterfucker Manual series. Would it be permissible to have my characters sleep with, say, Halsin, Yurgir, Oyaminartok, Glabbagool, Large Luigi, Visil'Taphenos Meadswimmer, etc. lol

just learned about Glabbagool

Just wait until you meet Glabbagool forgottenrealms.fandom.com/wiki/Glabbag...

3. Probably Glabbagool. They went to weird places.

The start of maybe the best email ever, I got this today:

“Hi Will,

Your character for tonight will be a sentient gelatinous cube named Glabbagool. Its stats are the same as a normal gelatinous cube except that it has an Intelligence score of 10 (+0) and telepathy to 60'.”
