Wrap the Mummy (or mommy as the case may be). Takes a couple of rolls of toilet paper. Really there's no point to it other than they have to wrap someone up and he/she has to be able to walk when they're done. You can put the kids in teams and make it a contest. Cheap TP works best (you know the thousand sheets on a roll).
Guess the number of candycorn in the jar. Closest guesser gets to keep the candy.
Instead of bobbing for apples sticking or spooning for apples. Best done outside or in a garage or on a plastic tablecloth or get plenty of towels. Put four or five apples in a pot of water filled to within a couple of inches of the top. Make sure there is lots of room in the pot for the apples to move around. A canning pot or large spaghetti pot works best. Prepare a second pot of water. Give kids drum sticks or wooden spoons. They have to transfer the apples from one pot to the other using only the drum sticks or the handles of the wooden spoons. You can use any other kind of long handles cooking implement but not something they can scoop the apples up with they have to balance the apples on the handles. It's tricky but they really get a kick out of it. The second pot is so that you don't have to keep moving them.
A take off on the egg race - Eyeball races. Take some old golf balls or pingpong balls and decorate to look like icky bloodshot eyeballs. Get some very small spoons (the shallower the bowl of the spoon the more challenging it is). Can be held in mouth to make it more challenging or do relays to make it more competitive.
Paper pumpkin decorating. Print out some pumpkin coloring pages and have the kids decorate them as jackolanterns using crayons, markers, confetti, construction paper, glitter glue, ribbon, bottle caps, stickers, etc (just whatever you have on hand). You can make it a competition to motivate them or just let them got at it. We've used, Jackolantern most unlike a jackolantern (it's amazing what they come up with), Jackolantern that looks most like me, scariest, prettiest. Let them decide what category they're shooting for.
