Are the goblins at your house getting pretty excited? To burn off some of that extra energy, have fun and develop large muscle coordination here is an imaginative idea. It needs a big, safe place for big moving around.
How would a witch move and travel? Swoosh and flit in your big, safe place. How would a skeleton move around? Shake, jiggle, rattle those bones. A cat stretches and curls as it walks on all fours. Try zombies, and bats, and goblins. Ghosts sneak around quietly, quietly without making a sound.
After lots of moving…sit and rest like a pumpkin. Ahh. Can you suggest some more Halloween moves?
