Guild Wars 2

Found this hidden area a couple days ago. Is the 1-Up really all there is to it? It went a bit deeper but there were dead ends along both paths. Came back today with 100% upgrades to play around with the flute just in case, but didn’t find anything.

Will there be more to it later on?

I just found this area today. I dug right on top of the 1-up and got 50 baubles, but 2 chests came out at the same time. So maybe its 100 baubles and it glitched out on me. Will try again later.
