I had thoughts of using clay and making one myself (after firing and whatever else I would need to do). But there is no way I can match the detail and design of the only ceramic brick I have (this thing is about 25 years old).
BTW, the ceramic brick I'm looking for is hollow for the little guys to play in. The bricks you mentioned sound like solid bricks.
