This deadly and completely toxic bright green watermelon mouthwash with peppermint oil kills immediately. Wait a second... oh no. Scratch that. It's totally not mouthwash, I mispoke, heh heh. Let's call it, uh, crushed emerald. Mmhm. So! This crushed emerald juice is incredibly fatal and can introduce death within 5 seconds of poison intake. It's a great method to have your worst enemies suffer, but not so great if your brother mistakes it for Mountain Dew.
