Melt butter and marshmallows together in a large pot on low heat. Mix in the Rice Krispies thoroughly and spread evenly in a 9 x 13-inch dish.
Melt chocolate in a double boiler and allow to slightly cool. Cut the bars in the pan into 3 x 3-inch squares and stick a wooden skewer in each. Dip the treat into the chocolate and shake off any excess chocolate.
Roll the treat in chopped nuts, colored sprinkles, or mini M&M's and allow the chocolate to set. When set, dip the treat into melted white chocolate slightly and allow it to set.
Set out on a platter and let the kids do the Hokey Pokey.
