Any ideas for a candy land castle?

Ok, ya it's weird but for my school we are supposed to make a castle girls against boys. It doesn't have to be that tall, maybe like at least 2 1/2 feet or a little taller. I had the idea of spreading chocolate frosting on the board where we r going to place the castle. And sprinkling little bits of died green cut up coconuts in random places for the gr. The castle is going to be made of rice crispy treats and the huge wooden door out of a Hershey's bar held up by two twizzlers for the ropes pulling the door up and down. We r going to stick dum dum lollipops in the gr for the flowers. The path way to the castle is going to be air heads, and rips for the flag on the castles. Idk what else can u plz help me!!! IDK WHEN IT'S DUE!!!
