I went to a haloween party when i was 15 and there were 2 very cool games.....
Bobbin' for body parts/bugs:
it starts off with a bucket of water (or pudding, ect..)and you put plastic body parts or bugs in the water. Blindfolded you must retrieve as many items before time runs out (use an egg timer or simply a watch)whoever collects the most items wins a PRIZE!!!
make a bowl of pudding and add plastic spider rings(or any small item)but a key element is to add one ring or small item that doesnt match the others. each person must stick their hand in one at a time and and grab just one item, whoever gets the different ring gets a PRIZE!!(they could grab with their mouth instead of their hands)try adding crumbled brownies to chocolate pudding for a mud like feeling)
