Turnip Cannon Jungle
From the Super Mario Wiki
Captain Toad will start on a high ledge next to the Power Star, but it's blocked off by a Rock Block. To destroy the Rock Block, the Captain will have to reach the Turnip Cannon at the bottom of the course, while avoiding the Piranha Creepers and Flaptors. When Captain Toad enters the cannon, the will enter a first-person perspective, allowing the player to shoot Turnips at the enemies and at the Rock Block blocking the Power Star. After destroying the block, Captain Toad will be able to access the Power Star.
A small hidden 8-bit Luigi can be seen on the ground behind the Turnip Cannon. It can only be seen on the while the player is in the Turnip Cannon. It can also be seen on the normal screen, but it is just a white speck.
