Free Roam in Mario Kart World provides players with a great opportunity to explore the tracks at their own relaxed pace. No one will be throwing items at you, so you can take your time and explore. There are even a bunch of collectibles for you to find as well, like the Question Mark Panels. These panels are well hidden in Acorn Heights, but if you want to collect everything in Mario Kart World you will need to track them down.

All Question Mark Panel Locations in Acorn Heights in Mario Kart World

First Panel

The first panel can be found immediately at the start of the track. Rather than going through the goal post at the start, turn around. Ride along the rail of the course and then jump off to land on the leaf where the first panel is waiting for you. The reward for finding this panel is an Acorn Heights sticker.

Second Panel

The second panel can be found shortly after the start/finish line of the course. Keep an eye out for a spot where the road splits, and on the left is a Yoshi’s Diner. Follow this path to reach the second panel.

Third Panel

From the spot where you found the second panel, continue onward and fly across the gap. While normally you would go down toward the track, fly toward the right to get onto the top of the cliff. There you will see the third panel. This panel unlocks the Wiggler sticker.

Fourth Panel

After claiming the third panel, drop down back onto the track. Don’t go too far though, as the fourth panel will be under a large leaf just before reaching one of the many P-Switches scattered across the game. Claiming this panel unlocks the Wiggler’s Sight-Seeing sticker.

Fifth Panel

While you are facing the fourth Question Mark Panel, turn around and head back. Drive past the P-Switch which will be on your right and continue down the track. When you see the Yoshi’s Diner, turn left. When you reach the spot where the road splits off into four different paths, go to the right and drop down into the grass. Proceed onward from here and go right through the tunnel. The fourth panel will be just after the coins. When you claim this panel, you will unlock a flower sticker.
