Super Mario Land 2: 6 Golden Coins/Macro Zone

On the top floor of this humongous house lies Ricky, the second golden coin holder. While he should be easy to defeat, the mountain tunnels leading to his residence has mysteriously shrunk you down to the size of a bug. You will need to dive into an anthill, make your way through the house's plumbing system, climb the house's fireplace and conquer the dusty attic to reach Ricky. Size is no excuse for giving up, so go ahead and go for the golden coin!
