I've shared sensory plays, crafts, themed baths, etc. for Halloween. Now I'm going to share a Halloween idea for play dough! Monster Eye's Play Dough!
I suppose you could use any color of play dough, but I chose green and I also had it be our eucalyptus play dough. Eucalyptus play dough is great for the season where colds are going around, it can relieve congestion while the child plays with it. To make Monster Eye's Play Dough you just stick googly eyes on/in the play dough.
