Silver-Shelled Snail (Pessimist and the Dromedaries)
From Jenny Everywhere Wiki
In the Prime Universe, a sarcastic Silver-Shelled Snail was one of the inmates at the Drove of the Database-Compiling Dromedaries' Research Laboratory 6 when Pessimist-242 was brought there. Like the others, the Crab took place in the mass escape orchestrated by Pessimist soon after. (PROSE: Pessimist and the Dromedaries)
