Iron

Iron, alongside diamonds and coal, is a currency used in the Robust Troll Series'. It was used in a shop in Robust town(that would not actualy give what it promised only give dirt back because it was a scam) at a exhange rate of 6.4 iron per diamond. It was a currency used in Cow Town, though with meagre value (about 2.5 iron per diamond according to Crainer) and was briefly used in Bee Town when Slogo moved in and hid his iron like hiding his diamonds. It was used to contact the builder in Cow Town, though would result in an intentionally messed up building, and was briefly used for hiding in Bee Town. Iron could also be used to make iron tools, helpful for building among other purposes. It was also briefly used as a currency in Squid island due to Crainer giving Jelly it in a apology gift. It was ( and to some degree still is with the exception being Crainer in Squid island) generally used more for tools than diamond. Pig Town saw the arrival of Jelly Inc, an industrial competitor to Slogo Worldwide that set its sights on taking over pig town. A Willy Wonka style factory was created to produce this iron, but it was soon destroyed with TNT by Crainer. In Squid Island marketplace, at least according to Slogo, a stack of iron blocks is equivalent to 2 diamonds. This means that an iron block is a thirty-second of a diamond. Dividing this by 9 to get the value of iron ingots to diamonds, we get a two-hundred-eighty-eighth diamonds per ingot, or 0.00347222222 diamonds per ingot
