Super Mario 3D World's Hands-On Hall level sends players to navigate through a structure that resembles a Japanese dojo. As they traverse this level, fans will have the opportunity to collect three Green Stars and a Stamp, though the locations of these collectibles may not be immediately obvious. For those Super Mario 3D World players that may be having trouble tracking down some of the Green Stars and the Stamp in World 6-3, this guide is here to help.

The first Green Star that players can collect in this Super Mario 3D World level is on the third floor of the first area. More specifically, fans should click on two sliding doors to open them and then approach the wall that is just past them. This action will cause the wall to swing open, revealing two Galoombas, a pile of coins, and Green Star #1.

The second Green Star in Hands-On Hall can be found outside, and Super Mario 3D World fans can use a Propeller Box, a number of which are situated on the right side of the area, to easily collect it. Simply, players should jump onto the Green Star in the gap once they have obtained a Propeller Box, and then activate the power-up to avoid falling to their death.

For the final Green Star, players will need to make their way back inside and past several Spikes that are pushing dangerous bars forward. They will then encounter a Warp Box, and there is a gong just beyond it that Mario should roll into. This will cause a Mystery Box to appear, and fans should enter it, defeat the Spike, and collect this Green Star in Super Mario 3D World.

To collect Hands-On Hall's Stamp, players will again be looking to the interior section with the Spikes, and they will need to have maintained the Propeller Box from the previous section. Fans should now position themselves in front of the first Spike and move in the direction of the bars that it is rolling. This will take Mario outside, and players can use the aforementioned power-up in Super Mario 3D World to reach the roofs and the World 6-3 Stamp.

While collecting Green Stars and Stamps is certainly not mandatory, they provide some fun optional content for those players that want to spend more time with the game. Indeed, tracking down all of the collectibles can significantly increase a fan's playtime, and that is undoubtedly something that many players will be interested in doing.
