Nitro Honey Syrup

Nitro Honey Syrup is a special syrup (presumably a sort of Honey Syrup) spoken of in Paper Mario: The Thousand-Year Door. Although Nitro Honey Syrup was never produced, recipes for it could apparently be found in the Businessman's briefcase. Although it is, by normalcy, powerful enough to perform miraculous acts such as even raising the dead, it becomes explosive when mixed with calcium and gold. The Shadow Sirens, wishing to put an end to the Excess Express (which Mario, their enemy, was riding at the time) in a "sticky, yummy explosion", decided to send their newest agent onto the Excess Express and have him steal the Nitro Honey Syrup recipe, correctly mix it into an explosive form (with help from Toodles's Gold Ring and the Toad Waitress's Shell Earrings), and finally destroy Mario. They would then frame Zip Toad (who Doopliss was disguised as at the time) for the crime so they could make off with the Garnet Star. However, they failed at doing so, and Nitro Honey Syrup was never mentioned again, although it is assumed that the Ratooey Businessman's company eventually managed to produce the miracle product.
