"Scientifc" drawing: internal anatomical view of a rat with one ginormous testicle and three smaller ones, attached to what appears to be a truly monstrous member extending upward into the aether. Three subpanels with dissection of testes. Labels are nonsense text: "senctolic stem cells", "testomcells", "iollottee sserotgomar cell", "spermatocial stem cells", etc.
