Riddle

I haven't posted in a while so I am posting now.
I made up a riddle! Here it is:
Moo goes the fish, Baa goes the cow but then what does the goat say?
Want the answer? Look for it!

Did you find it?
An answer could be "Goats don't talk!" But that would be stupid.
If you figure out the answer email me and I'll tell you if you're right!
Potatoes.
