Guess what the dead man ate for his last meal. Gooey guessing game
Large bowl, green or red jelly, creeply crawley, platic worms moggots, bats, bones etc. necker / blind fold.
In advance make up a big bowl of jelly - make it slightly runny by using a little too much water so it's more like green or red 'goo' rather than firmly set jelly.
Drop in your creepy crawlies and other bits and bobs.
Then gather the kids round and blindfold them in turn so they can dip their hands into the goo and guess what the dead man ate for his last meal!
