Sounds from toys

i have seen many toys wich make noises and i once ripped open a toy cat wich meows when you squeeze it  the circuit inside seemed so simple and i want to beable to do somthing like it.

is there any way i could make somthing that justproduces one sound (but not a beep) this simple or is it only possible on a mass production scale 

thanks

Did it have a black "blob"

Did it have a black “blob” somewhere on the PCB? that’s a microcontroller, you’ll need one for simplicity.

The synth is very flexible, its easy to make, gun shots, buzzes, musical tones, deep bass, engine sounds, whatever you want.
