Can you help me with circuit bending
 

Does anyone have a clue on how to take a toy with sirens, lazers and other sound effects and circuit bend it so I can control the pitch & tone of different sound effects? I just looked some stuff up on ebay but I'd rather make it myself...

sounds cool, good luck

Depends on the toy. You probably can't do that with newer toys. There's all kinds of websites/forums for this kind of stuff.. just look up circuit bending on google. Oh, I see people above me have supplied websites.

Whatever you do, do NOT circuit bend anything plugged into mains.
