So, I'm currently working on getting a breeding pair of Sea Serpents (Modded to give myself a chance of this happening, instead of just ending up with capturing the Biome's only one.), and I was wondering if this idea I had for them would work.

X - Wall
H - Hatch
SP - Screwpump
~ - Serpent
F - Floodgate
So I would wait until the gobbos or whatever is attacking gets into the chamber, and I close it off, then turn on the screwpumps, they fill the chamber, and they start drowning.
To make this more dwarvenly, the serpents start ripping them to pieces, now that they're able to move.
The problem I forsee with this model is they'd need to be chained so they stay in the chamber, but that would prevent them from swimming freely to eat the gobbos. Also, crossbows would take care of them before the chamber could flood.
This is my alternative model, which may be worse, or may be better:

This one uses grates surrounded by floodgates, a bit more space consuming, but I think it'd be better.
The flood gates would all go up once the gobbos were in the room (It's more of a vast chamber, 10 x 30 I'm thinking), and the screwpumps would start flooding it (More than two, obviously), the sea serpents would then start chowing down on delicious goblins, and once they were all taken care of, the inner floodgates would go down, allowing water to escape through the grates, and then the outer floodgates would open, allowing dwarves through. And the serpents would be immobile due to lack of water.
Version 2 is a bit more complicated, and would require more management on my part, but I think it'd be better.
Ideas?
