'-- YOU ARE HERE

Make your way under the bridge, then climb the ladder.

Weave your way around towards the bridge-like wooden thing in the center.

Hop onto the tree-like thing and when the two meet, head on over to the second one in order to grab Diamond #3.

Head back to where you were and you should see a pair of leaves by the bridge.

Pluck them to get a turnip or two and toss them at the other Piranha Creeper (an enemy that attacks when you get close) on this side.

With the path now wide open, head on straight and U-turn towards the ramp before stepping on the P-Switch (a button that temporarily alters the level).

Make your way to the newly accessible bridge, head forward and drop down, then head in the other direction.
