35-C is an alternate dimension that Rick and Morty visited in search of Mega tree seeds to aid Rick’s extremely important research… at least, that's what Morty was initially lead to believe. As it turned out, the seeds are contraband material that Rick needs Morty to hide in his rectum to smuggle past interdimensional customs. Morty reasonably complains the seeds are "pointy" and they hurt, which Rick states is good a thing, as it indicates the seeds are "good ones".
This design is a 3D scan hijacked from interdimensional customs, depicting Morty’s rectum harbouring rounder, sphincter friendly Mega tree seeds. Buy this SAX Tee now from an infinite number of universes, dimensions and realities. Portal gun sold separately.
