"Have a little fun with one of our sound-reactive graphical fish mouths. Be Frankie the Fish, a kissy-face puffer fish or whatever suits your taste. Simply choose a mouth and put your phone to your face. Now talk, shout or SING! Or, just hit the music button and get your Fishy-Fishy on with a serenade from your favorite mouth."
