the last 30 seconds are silent. other than that this is really cool

Awesome.

A good find of audio

For sure has a nice mario themed sound here I really liked it so nice job indeed, would have liked if this was a tad longer, Glad to find this one among all your great audio pieces you really know how to make some of the best music on here with all the "GREAT-SOUNDS-AND-EFFECTS" that go with it all, the quality is as always amazing and you bring some "VERY-NICE-AUDIO" to the portal.

It's 30 Seconds Long!

It's nice and spooky while it lasts, though. If only it actually lasted the whole minute.

It's so short its so short -_-

hmm maybe cause the ACTUAL mario underground music doesnt go for that long either?
ohh btw great job :D
