Crafting an item? Get a low-percentage chance of creating a "shiny" variant (a'la pokemon). Functionally identical, but with a modified colour scheme and/or extra graphical effects. Basically the same as rolling a UV, but handled seperately (ie: you wouldn't have to re-roll a UV to re-roll a shiny, and vice versa); maybe make a multi kilocrown ticket at Punch to shiny an already crafted item.
Because at the end of the day, it doesn't matter what you kill. What matters is how good you looked killing it.
