There are three Green Stars and a Stamp for players to find in Super Mario 3D World's Really Rolling Hills level. While overall these collectibles are fairly easy to obtain, some of them can only be collected after certain criteria have been met. Providing details on those criteria is the exact purpose of this guide, and players that read on should have little trouble collecting all of the Green Stars and the Stamp in Super Mario 3D World's World 2-4.

In order to collect the first Green Star in this Super Mario 3D World level, players must first assume Cat form. Fans should then go through the first clear pipe in 2-4 to reach a ledge with number of coins. From there, players should use their Cat skills to climb the dirt wall behind those coins, and they will find the Green Star when they reach the top.

There is a green pipe on on the bottom floor of 2-4's underground section, which Super Mario 3D World fans can enter after breaking through a couple of purple blocks. This pipe leads to a room that is covered in floor tiles that will turn various colors when walked upon, and the goal is to activate them all. Indeed, the second Green Star will appear as soon as that has been done, and players will be free to move onto the next collectible from there.

The final Green Star in Really Rolling Hills is also in the underground section, and it is, in fact, extremely close to the pipe that was used to access the color tile room. Specifically, players should fall between the rotating wheels that are just past the pipe to reach a lower level with several Question Mark Blocks and the Super Mario 3D World collectible of interest. There is also a green pipe in the area that fans can use to make a quick getaway.

With respect to the Stamp in 2-4, it is back at the very beginning of the level, and it can only be obtained by Mario. Simply, players should head to the right as soon as they enter Really Rolling Hills to reach a small island with a Character Switch sitting upon it. Fans should then jump on the Switch and collect the Stamp that will appear just above their heads.

Super Mario 3D World + Bowser's Fury is available now for the Nintendo Switch.
