Kirby: Canvas Curse

Hints: Find More Medals
Canvas Canyon: In Bloo Hills. At the beginning, proceed until a hidden doorway shows on the map. You'll find a medal inside.
Growth Grasses: In Arrange Gorge. Below the first Continue point, you'll find a hidden doorway. Draw a rainbow path to this and you'll find a hidden medal inside.
Machine Mansion: In Neo Greo. Use Missile Kirby to destroy a secret door guarded by blocks to get the hidden medal inside.
Ravine Road: In Reddy Land. After the first Continue point, you'll hit a speed booster that sends you forward. Look for the medal behind you in the upper-left corner.
Silver Submarine: In Iello Adventure. Use Stone Kirby to get this medal. Flatten the post then drop into the water to get the medal.
Spectacle Space: In Wonder Lilane. Look for the wall you can break near the beginning and tap it with your stylus to destroy, then follow the path to the medal.
Volatile Volcano: In Omarine Zone. After the first Continue point, there is a path to the right. Roll through the wall, hit the switch, then quickly get the medal.
