Mario &Luigi RPG 3 - Dark Area (fusion mix)

[HaruhiSuzumiyaGalaxy]

The Energy Hold was very chilling for me because the music fits the Boo-ray Machine. Call me crazy but I think I hear heartbeats at the beginning.

It's called 'The Road Leading to the Secret' in the soundtrack

[LuigiMan200]

Bowser's Path. THAT'S what it is called. Love the fusion mix by the way. ^^

[MasterKingPorky]

Bowser's Path as well as Yikk Tower, the Trash Pit, the Energy Hold, and the Underground Railroad.

and Toad Town Caves

The name is Dark Area. By the way, epic remix(Deserves 5 stars).
