Instructions
Go to the fourth level called Mustard Mountain. Go straight up in the hub world, where the Amazing Mirror itself lies. Press the Up button and take the right-hand door to enter the mirror with a stone frame.
Head right to pass through this level area. Avoid enemy attacks to avoid taking damage. Take the door at the end of the level.
Continue moving right. You will pass a "Minny" enemy trapped by a bomb block. Take the door at the end of the path.
Find the Cherry Spray Paint in this room. It will be shaped like a canister and will have a flashing background.
Head right and collect a 1-Up from the next room.
Go right once more to enter a mini-boss fight with Bombar. You can damage him with any of your attacks. Avoid his bombs as he drops them. You are also fighting strong winds which will try to blow you toward him. When you defeat him, you can claim the "100-Second" goal and return to the Hub world.
Open the "Treasure List" menu, and select "Kirby Colors" to change Kirby into his new spraypaint.
