Snails are an important part of the Mechanicsburg diet.
The reason for this is that, historically, the “water of the Dyne caused the snails to grow huge and they had a choice, blow them up or eat them.
Turns out, they are tasty!”
The 2012-05-11 (Friday)✣ comic has a shop selling Markyys Brand Snails ("Slow and Sweet"). A sign on the shop says "Green Devils are In!". There is a zine called Green Devil Face, issue 4 has a "mini dungeon" called "House of Snails". "Green Devils" was also a nickname of the Fallschirmjäger in WWII.
