So, now we've reached the second rarest type of Rupee you can find, whether in chests or dungeons. I don't know if it's because of their colour, but I had to search in the right place (the Bee house) to get my hands on it. Not too valuable to be kept, large enough to fill your pockets. Still, I don't find it worth to exchange every bee for them... (later on, I'll put a spoiler for the Gold Rupee)
