I have an idea. Because the Shenanigan Dimension loves triangles, it would make sense to say that it summons triangular objects to live in the SD. Because of this, I don't think it's to far fetched to assume that the reason all of us are here is because we have triangular shaped brains behind our craniums. That, or because of the amount of radiation seeping from the floating triangles, our brains have been morphed so that we have triangle shaped brains and all we can think of are shenanigans. Just a theory though.
I thank me, my brain, and the SD for helping make this.
