This piece is one of my first mimetolith "discoveries". As are all the mimetoliths in the collection, it is a one of a kind piece and is extremely unique. Rub-a-Dub-Dub has depth providing so it seems, it's own frame. The top and right top corner are comprised of primarily crystals while the bottom and bottom left corner have a "soft serve ice cream" appearance. The back (as pictured) which is actually the bottom of the specimen is relatively thin as shown in the detail pictures.
