Not an expert on Fukuoka dialect, but I could somehow read B's line with no problems.

「～～ごた/ごたあ」 means 「～～のような」 = "(just) like ~~". You might be familiar with the somewhat similar-sounding word 「[如]{ごと}き」 that means the same in Standard Japanese.

「水のごたまずかおかゆ」＝「水のようにまずいおかゆ」 = "rice gruel that tastes as bad as water" (It means the gruel is very thin.)

Fukuoka has ka-adjectives when the rest of the planet has i-adjectives.

Other dialectal words used:

「こげん」＝「こんなに」

「大きか」＝「大きい/大きな」

「やおか」＝「やわらかい」

"What did you have for breakfast?"

"Terrible-tasting rice gruel as thin as water (served) in a bowl this big and (very soft pickled plum...)"
