World 7-3 (Super Mario 3D Land)
From the Super Mario Wiki, the Mario encyclopedia
Seventy Star Medals are needed to unlock this level. In a dark tree level based on tightropes, Mario needs to navigate up a tree by tightropes while avoiding Fuzzies then jump in a Warp Box to get to another tree and do the same. If he looks into the Binoculars at the checkpoint, he will find five Toads (red, yellow, blue, green, and purple). The red and yellow Toads give Mario a Super Mushroom each while the other three cheer him on. After he hops into the next Warp Box, Mario is taken to the third and final tree. The player needs to avoid Fuzzies and reach to the flagpole. However, a huge shortcut requiring Tanooki Mario or Statue Mario is present in the stage.
