I made this by bending a simple amplifier circuit.  The tentacles have metal strips down the side and by touching each side of the tentacle simultaneously you trigger the sounds.  The sounds are a little unpredictable depending on the humidity and how conductive the wearer is.   Bending the tentacles also seems to have some effect.  Noise tentacles yeah!
looks like something from Mardi Gras
 Really cool but kinda creepy. lol
haha, nice. I could spend hours doing that. xD
