Thwomps might have villainous intent, but the spiked cinder blocks still manage to be a little cute. Instructables user mactothefuture made a replica of the Thwomp from Super Mario Bros. using a mold box and casting the block from concrete. I wouldn’t call it a simple process, but all the details are there if you’d like to try to make your own!
Check out more photos of the Thwomp after the break.
