Add the tub of frosting to a piping bag, and snip off just the very end.
To assemble, place the chocolate squares onto a parchment lined pan or cutting board, logo side up.
Take one unwrapped Reese's cup and add a bit of the frosting to the small end.
Press this into the middle of the chocolate square.
Repeat for all of the chocolate squares.
Flip these over carefully.
Take the airheads candy, and cut off a 1 inch piece, then slice the candy to separate the colors. You'll need 18 pieces.
Take an M&M candy, and add a dot of frosting. Place this into the middle of each flipped over chocolate square.
Repeat this for a matching piece of the rainbow candy to make the "tassle."
Chill in the refrigerator until ready to serve.
