With much inspiration from other photos on CC, I made this for my son's 7th birthday. I used a 10" round , 2 9" rounds, and pyrex casserole dish (for the rounded top part) all stacked up. I didn't need dowel rods or cake board because the pound cake was pretty sturdy. Covered in fondant, with buttercream between layers and for the crumb coating. My son loved it so much, he wouldn't let me put candles it it...ha ha!!
