how do i beat that water bird the 2nd time in the sewer? and whats the best what to beat it?

i just ran for my life and attacked rite after it did

First, transmute all the nearby junk you can into cannons. The Sea Chimera pops up in different pools of water, and there are like 2 cannons you can transmute near every pool...if you really want to, have Al man a cannon. Once you see it come out of a pool, IMMEDIATELY hop onto a cannon and unload it's shots into the Sea Chimera. It's actually pretty easy, especially if Ed's Alchemy Stat is high...

like the poster above me said,turn junk into cannons.then immobolize it,attack it with something lightning,then run for your life.use magic caps to help you out also.i defeated all FMA games like,five times.

what magic caps? and also i dont have any reloader metals i know there are some there but there arnt enofe to beat it
