i already loved intellect devourers, they're just little brains with legs and tentacles, so i was absolutely overjoyed when you get one as a follower in BG3. i finally got around to making a plushie of the design from the game, though im super in love with the canonical design and that of ustilagors that seemed to inspire the in-game look of them.
you can see more photos on my ko-fi and because i think that this guy is so cool, i posted a public blog post about how i went around designing this plushie(and taking a moment to despair about other brain plushies on the market today)!
