This "demon" from Otherworld miniatures has some bite to it...
Not sure how tall he is though.
Scale wouldn't really matter for deep ones, since Dagon is bigger than his fishy tykes.
Well, I found out how tall. He's very close to the same
physiological height (regardless of pose) as this new fellow, who's much chunkier:
The first miniature from Nameless Design Miniatures (aka Roebeast) is now available! The Giant Deep One is a massive monster from the depths, certain to frighten the most stout of heart adventurers or investigators. The miniature comes in three parts and includes a 40mm round base.
Price is 8.00 USD plus shipping and handling. S&H for The US is 2.00 USD and International is 4.00 USD. Please go to http://roebeast.blogspot.com/2010/11/giant-deep-one-now-for-sale.html for more information.
Sorry but I don't have the Grenadier Deep Ones for reference. Hopefully this gives you a better idea. And the ScaleStick is a little off in this picture since the minis have integral bases.
Young Father Dagon and Mother Hydra? :O
BTW... the metal Scale Stick is available for $5 - and I recommend it, especially if you have a mix of older 25mm and newer heroic 32mm figs:
