In a medium mixing bowl, combine crushed cookies, hazelnuts or almonds, powdered sugar, corn syrup, orange juice, and butter. Stir with a wooden spoon until well mixed.
Shape mixture into 2-inch oval shapes, using 1 tablespoon dough for each. In a small saucepan, melt the candy coating over low heat, stirring until smooth. Remove from heat. Place one oval on the tines of a fork. Holding fork over saucepan, spoon melted candy coating over oval until completely covered.
Tap bottom of fork on edge of pan to remove excess coating. Use a small metal spatula or table knife to push the coated oval onto a sheet of waxed paper. Press a jelly candy in the center of each oval.
Affix a candy-coated fruit-flavored piece or milk chocolate candy piece in the center of the jelly candy using a small amount of candy coating. Let stand on waxed paper until the coating is set. Decorate with red writing gel, forming eyeballs.
Snip large gumdrops into small pieces and press together on a well-sugared surface, four at a time. Roll to about 1/8 inch thick, combining different colored gumdrops together, sugar generously.
Cut into 2-1/2-inch ovals (or cut the fruit leather into 2-1/2-inch ovals). Press two of the ovals around the eyeballs, forming eyelids. If not sticky enough, melt additional candy coating and spread on the inside of the eyelids before pressing against the eyeballs.
