New project: make every Soyjak have multiple rows of teeth

Every time a new variant appears, it goes through the usual iterations: gem skin, coal skin, calm, neutral, pumpkin etc. Let's add a new variation to the repertoire: "Multiple rows of teeth". Furthermore, we should go back and draw each variant as having multiple rows of teeth. We'll call it Operation #makeeverySoyjakhavemultiplerowsofteeth .
