Oh man, what a treat to find new fun monsters. Here's a few off the top of my head.
The Charnal Hound from MMIII - It's like a mini, one-headed Cerebus that eats the corpses of your friends. What's not to love?
The Catterprism from Tome of Horrors II - Aw, it's a big ol' catterpillar! That just encased... my friends... in crystalline webs... and chomped off their heads in...a single... bite? Vorpal biting giant crystalline catterpillers! I love 'em!
I like the Oodopi from MMIII for no other reason than it looks so funny. A ball of arms with eyes in the palms, its a big, living Koosh ball!
The Crucifixition Spirit from Tome of Horrors II - It caused my players to throw dice at me, which is usually a sign that I've done a good job of being a Rat Bastard DM. Touch attack equals at least 2 negative levels and possibly more? That'll teach those PCs that think they're invincible!
All the many kinds of oozes from many books, the dun pudding, crystalline ooze, white pudding, and several others from Tome of Horrors, arcanoplasm from Tome Horrors II, and all the fun new oozes from MMIII (snowflake ooze, summoning ooze, arcane ooze, and all the living spells). What can I say, I like oozes. It's my dream to be able to play an awakened ooze some day...
