I feel like celebrating the return of the Dungeon Dozen to the internets so here's a few super specific encounter tables:
These use regular old d6s rather than the exalted dodecahedron.
What does the Moon Beast do this round?
1 run away. They'll stop in the next room and attempt to ambush anybody who follows.
2 knock stuff over, onto PCs if possible. If the only thing available is a person, they'll knock them over and stand on them. Save vs paralysis/fortitude/yeti stompin or take d4 dmg. Save again to act or wrestle free.
3 amazing leap onto the largest inanimate object nearby and screech/howl loudly. The following round a return call of screeches/howls may be heard. Another 1-3 Moon Beast 4-6 two Moon Beasts shows up in d6 rounds.
4 pick up one PC and throw them at another PC. Both PCs Save vs paralysis/fortitude/yeti stompin or take d4 dmg
5, 6 attack w claws, two attacks: d6 dmg. each.
Moon Beasts are big uni-horned, white furred yeti type critters with a primitive inteligence. (stat as bugbears exept as noted above)
What's up with the Ghouls in this room?
1 Ravenous. as many as possible will attack and attempt to devour whoevers in front. Attacking them back will draw their attention away.
2 Curious. They're throwing everything not nailed down around as if they were 2 year olds. If spoken to they will grunt back in imitation, and speak Ghoulish. they'll continue this for d3 rounds at which point they'll realize the PCs are food an attack.
3 Sullen. Theyll fight but 1-2 on d6 chance of running away every round.
4 Fighting eachother over a 1-3 live 4-6 dead thing.
5 Stalking something else, roll another wandering monster.
6 Awaiting the PCs in ambush.
All Ghouls used to be elves. They are 1-12 feet tall, and are from an invisible moon, where the elves sent them. They are not very bright, but they do have their own language, Ghoulish, which is a gutteral perversion of ancient elvish.
Their claws cause paralysis just like the book says.
