7 HD is fine.
Fine (or should I say Diminutive?).
I'll update the Working Draft with 7HD and 4HD for the swarms.
I suppose we should talk damage. The original did 3d6 damage (or 1d6 with a save vs paralysation) to all creatures within a 10 foot radius.
We could average that to 2d6, or give it 1d6 with some "special attack" that increases the swarm damage by +2d6 with a save (Ref?) to negate.
