Spread the chocolate frosting onto the Suzy Q cakes, and sprinkle a layer of the crushed Grahams on top.
Color the vanilla frosting green and put it in a plastic baggie. Place a few pumpkins on each cake and make some curly leaves/stems from the pumpkin to the dirt with the green frosting.
Write the word pumpkins on each round wood piece and glue each one to a craft stick using a hot glue gun.
Stick a sign into each cake.
Sprinkle a little bit of the green candy shreds or autumn sprinkles in a few spots to look like grass.
