If you buy the sound module in the pic......don't forget about needing to lower the DC voltage.....
I found this advice on the Internet about dropping 12V DC down to 5V DC...................
Cut two pieces of electrical wire. Strip ½ an inch of insulation from the ends of each wire. Verify that the power supply is turned off.
Twist together one end of the first wire with one of the leads from the 1.4-kiloohm resistor. Connect the loose end of this wire to the positive terminal on the power supply.
Twist together the free lead from the 1.4-kiloohm resistor with one of the leads from the 1-kiloohm resistor.
Twist together the free lead from the 1-kiloohm resistor with one end of the second wire. Connect the loose end of this wire to the negative terminal on the power supply. Turn the power supply on
Turn on the voltmeter and set the scale to measure "Volts DC." Place the black voltmeter probe on the electrical joint between the second wire and the 1-kiloohm resistor. Place the red voltmeter probe on the electrical joint between the two resistors. The voltage across the resistor will be approximately 5 volts.

look up "billy bob hack". people hack those fish noveltys all the time. I actually have a tilly the talking Christmas tree I hacked for a similar type project, using the motion detector and the servos as well...
