My son Patrick turned 8 and we threw him a minecraft party. It was really simple to do and he loved it!
First off the details. I made "potion" with a tub of lime sherbet and a 2 liter bottle of sprite. Then I crafted a cake out of 2 different sheet cakes and 2 different types of rice crispie bars. It had a bridge, lava, a diamond mine, animals and grass. Really pretty simple with frosting and a little creativity. We covered our stairs with "lava" to keep kids from going upstairs. I used little aliens err.. "creepers" to hand out as a party favors. A nether portal was just a plastic table cloth over our entry. Foam swords were a big hit as came in handy for the TNT piñata (just a box with tissue paper around it) We had a diamond hunt (small plastic crystals from the party store) that we hid in the sandbox. The place cards also served as clues to help find the diamonds. We finished off the party with minecraft projected on the big tv, although the boys quickly lost interest in that and headed outside for their own minecraft adventure.
