You are correct. Echohawk doesn't have it on the unconverted list, since it was converted by Vaults of Pandius. We can do our own version if you'd like, or we can move on to one of the other unconverted animals.
Sorry, I left out the full explanation.
I already knew of the Vaults of Pandius
conversion, but that's not the Weed Eel in question.
I'm talking about the AD&D version of the Weed Eel (the variety that lives in communal tunnels and has a deadly poisonous bite) that's in the
Monster Manual (1977),
Monstrous Compendium Volume Two (1989) and
Monstrous Manual (1993).
The BECMI version converted in the Vaults of Pandius (an eel that looks like seaweed and grapples/drowns its victims) may share a name, it's a different creature.
EDIT: I've just checked the AC9 version of the Weed Eel and it has a poison bite, but the Vault of Pandius conversion forgot to include it! :ENDEDIT
If we do decide to convert the weed eel, it probably doesn't belong in this thread (since it didn't appear in Dungeon, as far as I can tell).
What? Isn't this the "Converting "Real World" Animal and Vermin thread"?
Glances up to the top of the thread...
Oh shazbut, I posted it in the wrong place.
We'd better move this conversion to somewhere else. As far as I can tell the AD&D Weed Eel is not based on a real-life fish, so some other thread like the "Monstrous Compendium" or "First Edition AD&D" creature threads may be more appropriate.
Getting back to this thread, I'll have to check the unconverted Dungeon monsters list to see if anything tickles my fancy.
