My R2D2 cake that I planned for well over a month for my son's 6th birthday party. It definitely was a labor of love, as it was a big PITA to assemble. My buttercream melted and my fondant bulged, causing me to do it over. In the end, it wasn't as clean as I had envisioned, but it was a HUGE success with kids and parents, it tasted awesome, and, most importantly, it stayed standing throughout the entire car ride and outside party!
