How To Get Shiny In Big Walk For Big Makeover Achievement/Trophy

Once you’ve done that, you’ll want to start at the big, red, circular hub where each session begins. I took to calling it a gym or a playground, so I will refer to it as “the gym” from here on out. From the gym, head through the gap to the right of the map room. If you’ve not yet opened the map room or the shortcut door to the right, it’s the one in the image below, but the same goal can be achieved if you just explore and enter any tunnel entrance, since you’ve at least gotten tunnel access by now (or else you shouldn’t be using this guide yet).

Continue along the trail with an unclimbable rock wall to your left. After about 30-60 seconds, you’ll see the red tunnel entrance on your left. Enter the tunnels via that opening. There will be a flashlight there if you need it, and I recommend taking it unless you already have a different light source. 

At the end of this hallway, you can only go one way: up a long, narrow staircase to the right. Head up those stairs, and you’ll be met with a corridor where you can go in one of two directions, with signage on the floor indicating the directions to take in order to reach the yellow or green tower. Though both could get you to where you want to be, the path toward the green tower is best, so head to the right. This will send you through a hallway that shifts colors from blue to red and eventually yellow. Just keep going straight until you see a green door ahead, which you’ll then enter. You’ll now be at another crossroads: Left takes you to the blue tower, while going straight will take you to the green tower. 

Go left into the blue corridor, which will look like a big ramp you’re walking up. You’ll go through a doorway into a narrow hall. Head left in this hall, and the blue hallway will turn green and then red. 

Up ahead, you’ll see a small grey door, which leads to a different secret that I won’t spoil here, but that I recommend you check it out if you haven’t yet–just remember how to get back to this location. 

After not going through the grey door (or doing so and finding your way back) take a left through the red, spiraling hallway. 

The corridor will again change colors, this time to green. Keep going straight through the green hallway and enter a small red door once you come upon it. This door will stick out because it’ll feature a circular paint pattern around it that uses red, blue, and green paints in a manner nowhere else in the tunnels does.

Once you’re through that door, you’ll find yourself on a staircase with purple walls. Jump or walk to the very bottom of the stairwell, and you’ll find what you’re looking for: another paint studio, only this one has three additional colors–bronze, silver, and gold. 

Remember that, like with many of the game’s items, you can’t use the paintbrush to color yourself. You’ll need a partner to paint you. Once any of the three shiny colors have been applied to your character, you’ll unlock the Big Makeover Achievement or Trophy–or, on Switch, you’ll just look really cool.
