Mario and Link!

Ha ha the OS team did the scavenger hunt and found a place where Link is standing next to Mario, but.... did you read the whole description?

Find the place where Link is standing next to Mario and is playing a tune from Legends of Zelda: Ocarina of time

It seems the place you found is the Nintendo-related store, and I don't seem to remember Link is playing a tune there.... The place I mean allows you to click on Link and you can actually hear the tune, and it looks like the picture above.

Now I dare you: find this place! :)
