OT: toy megaphone schematic?

[mungenast@earthlink.net]

Hi gang:

Anyone know where I can get a schematic for the toy megaphone made by a 
company called PC Sound?
It's a purple-and-fuschia megaphone that does awesome robot sounds etc.
I made on eintoi a stompbox and now I need some guidance, esp. a 
schematic. 

Thanks,
Tim
