Thanks all for the wonderful help! The show was Sunday and I asked the question a little late but I did manage to figure something out. I didnt have time to order the sheets of RKT from food service and I just wasnt liking the look of any of the homemade recipes I tried (although I have sense saved the website posted, thank you). I already had the styrofoam dummy so i knew i just needed to get something to cover the outer part. I found that the pre-packaged RKT from Kellogs were a good look but they were not soft enough to smash together without having huge seams where the treats met. I happened upon large boxes of Little Debbie RKT at walmart and thought i would take a chance. They are a little more yellow in color, but once on the "cake" they looked wonderful. I am extremely happy with the final outcome and to do the dummy, I didnt even need 3 of the boxes of treats for a total cost of around $10. Now when someone orders this I can do the homemade treats on the inside to form into blocks and cover with these treats. The final outcome is in my photos. Thanks again all!!!
