Comment on Plankton (Commission) by Kyle-Dove

I really dig the concept of these two, especially how the kanjis are incorporated, and the colors! But I really can't get my head around how they would look tridimensionally... I imagine the first one is quite flat, like unown maybe, but what about its evo? Is it more spherical? also is the big bar on the "blob hand thumb" like a katana? And does it have two yellow eyes or a single eye with a green pupil? sorry for all the questions
