Hi for this project I have chosen the following toy:
that when you press on the yellow circle on the tummy makes a frog sound and when is shaken makes noise..
Now the big question what makes this toy to make this sound. So, let see fist I cut the stitches on the back of the toy. Then took out the material that that made the toy soft.
The following image show all the pieces from the sound part including the battery.
And on the end this is the pattern of the soft toy including the manufacture label.
