My son asked for a bugs and worms cake...the bottom tier is covered in oreo cookie crumbs with a carved out any hill, the ants are made from raisinettes and royal icing, gummy worms crawling in and out and centipedes made from m&m's and royal icing. The top tier has fondant grass with m&m ladybugs and oreo butterflies. The 4 is made from gummy worms and royal icing.
