I used to make Xmas treats like whiskey balls or schwedy balls but now I make a treat inspired by Monty Python called Crunchy Frog.
I take whole half walnuts, that look like the body of a small frog and in a double boiler I melt Dove chocolate to dip the walnuts and set down on wax paper. For the chocolate head I make a head out of epoxy, this takes bit of sculpting skill, to make a mold out of several thick aluminum foil sheets and pressing the head shape into the foil. I dab the chocolate into the mold and attach the head with some more melted chocolate. For the eyes I use a tiny round confectionary before the chocolate is cold.

You can make brown red or brown green versions but who cares, they taste alike unless you add peppermint oil to one batch or a hint of cinnamon to another.
