Miniature Cinder Blocks
My new lady friend, She-Ra: Princess of Power, has a chinchilla named Albert (not as cool as a hedgehog, but way better than a chihuahua), so I was thinking of getting some of these miniature cinder blocks to build him a fortress for protecting himself against a possible armored guinea pig attack. And also to give myself something to do when She-Ra tells me she's "almost ready", but then I still somehow find myself sitting around her condo with nothing to do for the next 23 to 74 minutes.
The blocks are perfectly modeled, real cement cinder blocks scaled to 1/12th the size of those you're used to dinking around with. Hobbyists and other bored people at the mercy of someone else's primping schedule can choose from sets of 10, 24, and 50, plus a grab bag of broken blocks for creating crumbling or distressed structures. Miniature cinder block sets come with a mix of stretchers and pillars.
